In a casual reading, the story at the beginning of Luke chapter 9 doesn't seem to have much relation to the events of the previous chapter. But, looking deeper, it does.

At the end of Luke chapter 8, when the little girl who seemed to be dead was brought back to life, Jesus commanded that her parents give her something to eat. In sacred scripture, giving someone “something to eat” is about spiritual nourishment. It refers not only to teaching, but also spiritually nourishing one another with words of encouragement that align with spiritual truth. To the extent that we do this for one another, we become God’s disciples and apostles, cooperating with Him in the work of salvation. We are “disciples” while in His presence, learning from His Word. And we are His “apostles” when we are being sent out to minister to others, through our words and actions.

It's appropriate, then, that chapter 9 begins with Jesus calling together His twelve disciples, and then sending them out to minister to others:

“Having called together His twelve disciples, He gave them power and authority over all demons, and to cure diseases. And He sent them out to preach the kingdom of God, and to heal the sick” (Luke 9:1-2).

In a deep sense, the gathering together of the twelve disciples, before sending them out as apostles, represents an important step in our spiritual development. This begins when Jesus “calls His twelve disciples together” in us, which represents that time in our lives when we begin to understand matters of the spirit more deeply. Every “disciple” represents an essential spiritual principle. As we “gather” these principles together in our minds, striving to see how they cohere and relate to the larger whole, we begin to see the connections between ideas, and we develop a keener discernment between what is primary and what is secondary. As a result, we can apply the truth we have been learning more usefully in our lives. ¹

After gathering the disciples together, Jesus sends them forth as His apostles, giving them specific instructions for the journey. “Take nothing for your journey,” He says to them. They are not to take a staff, or a backpack, or bread, or silver, or even an extra change of clothes. Every word has spiritual significance. They will not be needing a “staff,” because they will be relying on the Lord alone. They will not need a “pack” to store up what they have learned, because the Lord will give them what to say. They will not need “bread” or “silver,” because the Lord will provide all the goodness (“bread”) and all the truth (“silver”) they need. And they will not need an extra tunic because they will be clothed in truth from the Lord, and will not need anything additional from themselves.

In this case, less is more. When there is less of self, there is more of God. ²

Shaking off the dust:

Jesus then says to them, “And into whatever house you enter, there remain, and thence go out. And as many as shall not accept you, when you come out of that city, shake off even the dust from your feet for a testimony against them” (Luke 9:4-5). A “house,” as we have mentioned before, represents the human mind. It is the place where we think things over, consider our options, and dwell on those matters that are significant to us. Our “house,” then, is our spiritual residence, our “dwelling-place.”

Spiritually speaking, everyone has a dwelling-place — a set of beliefs about themselves, about others, and about God. Because of this, some people will accept the teachings of the apostles gladly, while others will reject them. Knowing this in advance, Jesus tells them that if their teachings are rejected, the apostles should leave the house, come out of the city, and “shake the dust from off their feet.”

In sacred scripture, the term “dust” refers to things that are low and relate to the world of the external senses. Just as dust settles to the earth, there is a tendency to remain focused on things that gratify our worldly senses without lifting our minds to higher things. In the Hebrew Scriptures, this is represented by the lowly serpent who deceived Eve. As it is written, “So the Lord God said to the serpent, “Because you have done this … you shall eat dust all the days of your life” (Genesis 3:14). ³

Jesus’ instruction to “shake off the dust” is sound advice, not only for the apostles, but for each of us. Along the spiritual journey, as we are learning truth and putting it into our lives, we may, at times, find ourselves being dragged down to lower things — those things that are merely worldly and temporal. This is, spiritually, “the dust on our feet.” Whether the dust comes through the negative influence of others or the self-serving thoughts we entertain, Jesus tells us to “shake the dust from off our feet,” and continue our journey. ⁴

This is precisely what the apostles do. As it is written in the next verse, “And going out, they passed into the villages, announcing the gospel and curing everywhere” (Luke 9:6).

Footnotes:

3024.'That you do not take a wife for my son from the daughters of the Canaanites' means that the Divine Rational should not be joined to any affection incompatible with truth. This is clear from the meaning of 'taking a woman' as being joined by means of the marriage covenant; from the meaning of 'my son', namely Isaac, as the Lord's Divine Rational, dealt with in 1893, 2066, 2083, 2630; from the meaning of 'daughters' as affections, dealt with in 489-491, 568, 2362; and from the meaning of 'the Canaanites' as evil, dealt with in 1444, 1573, 1574. Consequently 'the daughters of the Canaanites' are affections incompatible with truth. The subject here is Divine truth which was to be allied to the Divine good of the Lord's Rational, as may be seen in 3013 under 'Contents'. 'A woman' who was to be associated by means of a marriage covenant is used to mean that truth itself which is summoned from the natural man in the normal manner. 'My son' is used to mean the Lord's Rational as regards the good with which it was to be allied or associated. From this one may recognize that the command not to take a wife for his son from the daughters of the Canaanites means that the Divine Rational should not be joined to any affection incompatible with truth. All joining of truth to good is effected by means of affection, for no truth ever enters the rational part of a person's mind or is joined to it except by means of affection, for affection has within it the good that flows from love, which good alone effects the joining together, 1895, as also anyone may know who stops to reflect on it.

[2] As regards 'the daughters of the Canaanites' meaning affections incompatible with truth, that is, affections for what is false, this becomes clear from the meaning of 'daughters'. For the noun 'daughters' occurs in many places in the Word, and in these anyone may see that it is not used to mean daughters. By such expressions as 'the daughter of Zion', 'the daughter of Jerusalem', 'the daughter of Tarshish', 'the daughter of My people', affections for good and truth are meant, as shown in the paragraphs referred to above. And since affections for good and truth are meant so also are Churches, for Churches are Churches by virtue of these affections. Consequently 'the daughter of Zion' means the celestial Church, and means this by virtue of the affection for good, whereas 'the daughter of Jerusalem' means the spiritual Church from the affection for truth, 2362. And it is the same with 'the daughter of My people' in Isaiah 22:4; Jeremiah 6:14, 26; 8:19, 21-22; 9:1; 14:17; Lamentations 2:11; 4:6; Ezekiel 13:17.

[3] This shows what is meant by the daughters of the nations, such as by the daughters of the Philistines, the daughters of Egypt, the daughters of Tyre and Sidon, the daughters of Edom, the daughters of Moab, the daughters of the Chaldeans and Babel, and the daughters of Sodom. They mean affections for evil and falsity, from which their varieties of religion sprang, and so mean those varieties themselves. That this is the meaning of 'daughters' becomes clear from the following places: In Ezekiel,

The daughters of the nations will lament over Egypt. Wail over the multitude of Egypt, and send her down, her and the daughters of majestic nations, to the lower earth, together with those who go down to the pit. Ezekiel 32:16, 18.

'The daughters of majestic nations' stands for affections for evil. In Samuel,

Tell it not in Gath; publish it not in the streets of Ashkelon, lest the daughters of the Philistines rejoice, lest the daughters of the uncircumcised exult. 2 Samuel 1:20.

In Ezekiel,

You committed whoredom with the sons of Egypt. I delivered you to those who hated you, the daughters of the Philistines. Before your badness was revealed, as at the time of the reproach of the daughters of Syria, and of all round about her, the daughters of the Philistines who despise you from round about. Ezekiel 16:26-27, 57.

Anyone may see that not daughters were meant here but the varieties of religion among such people as are meant by the Philistines - those who speak repeatedly of faith yet do not at all pursue the life taught by faith, see 1197, 1198. This also explains why they are called 'the uncircumcised', that is, devoid of charity.

[4] In Jeremiah,

Go up to Gilead and take balm, O virgin daughter of Egypt! Make for yourself vessels of migration, O inhabitant daughter of Egypt. The daughter of Egypt has been put to shame; she has been delivered into the hand of the people from the north. Jeremiah 46:11, 19, 24.

'The daughter of Egypt' stands for the affection for reasoning from facts about whether truths of faith really are true, and so stands for the variety of religion which springs from this, the nature of which is to believe nothing except that grasped by the senses, and so to believe nothing of the truth of faith, see 215, 232, 233, 1164, 1165, 1186, 1385, 2196, 2203, 2209, 2568, 2588. In Isaiah,

He said, You will no more exult, O oppressed virgin daughter of Sidon. Isaiah 23:12.

In David,

The daughter of Tyre with an offering, the rich of the people will entreat your face. Psalms 45:12.

What 'the daughter of Sidon' and 'the daughter of Tyre' mean is evident from the meaning of Sidon and Tyre, dealt with in 1201. In Jeremiah,

Rejoice and be glad, O daughter of Edom. Your iniquity, O daughter of Zion, is at an end. He will no more cause you to migrate; your iniquity will be punished, O daughter of Edom. Lamentations 4:21-22.

In Isaiah,

Like a wandering bird, a scattered nest, will the daughters of Moab be. Isaiah 16:2.

In the same prophet,

Come down and sit on the dust, O virgin daughter of Babel; sit on the ground without a throne, O daughter of the Chaldeans. Sit quietly and go into darkness, O daughter of the Chaldeans, for no more will they call you the mistress of kingdoms. Isaiah 47:1, 5.

In Jeremiah,

A people coming from the north, arrayed as a man for war against you, O daughter of Babel. Jeremiah 50:41-42.

In the same prophet,

The daughter of Babel is like the threshing-floor; it is time to thresh her. Jeremiah 51:33

In Zechariah,

Ho, Zion! escape, you who dwell with the daughter of Babel. Zechariah 2:7.

In David,

The daughter of Babel has been laid waste. Psalms 137:8.

In Ezekiel,

Your sisters, Sodom and her daughters will return to their condition as of old, and Samaria and her daughters will return to their condition as of old. Ezekiel 16:55.

[5] Anyone may see that in these places 'daughters' is not used to mean daughters but affections incompatible with truth, and so the varieties of religion that spring from them. But which particular varieties they are is evident from the meaning of those peoples - from the meaning of Edom, Moab, the Chaldeans, Babel, Sodom, Samaria, all of which have been dealt with in various places in the explanations to previous chapters of Genesis. From this what is meant in the present chapter by 'the daughters of the Canaanites' becomes clear.

[6] This command not to contract marriages with the daughters of the Canaanites also had regard to the spiritual requirements that good should not be joined to falsity, nor evil to truth, for the result of any such joining together is profanation. The prohibition was also a representative of the matter referred to in Deuteronomy 7:3, and in Malachi,

Judah has profaned the holiness of Jehovah, in that he loved and married the daughter of a foreign god. Malachi 2:11.
