300. As regards the first arcanum, that 'Jehovah God' is used to mean the Lord and at the same time heaven, it should be recognized that in the Word, always for some hidden reason, the Lord is sometimes called simply Jehovah, sometimes Jehovah God, sometimes Jehovah and God interchangeably, sometimes the Lord Jehovah, sometimes the God of Israel, and sometimes simply God. In Genesis 1, for example, where again an utterance is made in the plural, 'Let Us make man in Our image', God is the only name used. Not until the next chapter, where the celestial man is the subject, is He called Jehovah God-Jehovah, because He alone has Being and is Living, and so from His essence; God, because of His ability to accomplish all things, and so from His power, as is clear in the Word where the two names are used separately, Isaiah 49:4-5; 55:7; Psalms 18:2, 28, 30-31; Psalms 38:15. Consequently any angel or spirit who spoke to a person, or who people thought had the ability to accomplish something, they called God, as is clear in David,

God stands in the assembly of God, in the midst of the Gods will He judge. Psalms 82:1.

And elsewhere in David,

Who in the sky will be compared to Jehovah? Who will be likened to Jehovah among the sons of gods? Psalms 89:6.

And elsewhere in the same,

Confess the God of Gods; confess the Lord of lords. Psalms 136:2-3

It is from power that even men are called 'gods', as in Psalms 82:6; John 10:34-35. And Moses is spoken of as 'a god to Pharaoh', Exodus 7:1. And this also is why [in Hebrew] the word for God, Elohim, is plural. But because angels have no power whatsoever from themselves, as they themselves also confess, but from the Lord only, and as there is but one God, Jehovah God is therefore used in the Word to mean the Lord alone. Yet when anything is accomplished through the ministry of angels He is spoken of in the plural, as in Genesis 1. In the present chapter too, since a celestial man, as man, did not bear comparison with the Lord, but with angels, it is therefore said that 'the man has become as one of Us in knowing good and evil', that is, become someone wise and having intelligence.

Dust, in Ezekiel 26:12, signifies the lowest things which are of the sensual principle of man. They can be either good or bad, depending on the context.

In Isaiah 40:12, the dust signifies exterior or natural truths and goods of heaven and the church.

In Genesis 2:7, the dust is good, and we see some interesting nuances:

First, there's this: 'To form the man, dust from the ground' is to form his external man, which had not previously been man... (Arcana Coelestia 94)

Here, this formation of our external body and mind is a precursor, setting the stage for God to "breathe into our nostrils".

In Arcana Coelestia 1610, we find this passage, where again, dust has a good signification:

'Dust of the earth' has regard to those things that are celestial, for, as shown already, 'the earth' means the celestial aspect of love; 'dust of the sea' has regard to those things that are spiritual, for 'the sea', as has also been shown, means the spiritual aspect of love; while 'as the stars of heaven' means both but in a higher degree. And because these things cannot be numbered they therefore became common expressions to describe growth and multiplication beyond measure.

Then, in Arcana Coelestia 3707, these ideas get pulled together:

The reason the dust of the earth symbolizes goodness is that the earth, [or land,] symbolizes the Lord’s kingdom and therefore goodness, as shown just above in §3705. The dust of that land, then, means goodness, but earthly goodness, since the land symbolizes what is lowest in the Lord’s kingdom....

But there are bad connotations, too. In Micah 7:14-17, licking dust symbolizes being only sensual - bodily and external, worldly, and selfish. It's much the same in Psalms 72:9, where "Barbarians will bow down before God, and His enemies lick the dust...". See Arcana Coelestia 249, 3413 for interesting explanations of this.
