378. "And have washed their robes." This symbolically means, who have cleansed their religious beliefs of the evils accompanying falsity.

Washing in the Word symbolizes a cleansing oneself of evils and falsities, and robes symbolize general truths (no. 328). General truths are concepts of goodness and truth drawn from the literal sense of the Word, in accordance with which these people have lived, so that they are religious beliefs. And because every matter of religion has relation to goodness and truth, therefore robes are mentioned twice - "have washed their robes" and "have made their robes white."

Robes or religious beliefs are cleansed only in the case of people who fight against evils and so reject falsities, who thus undergo temptations or trials, which are symbolically meant by "the great tribulation" (no. 377).

That to be washed means, symbolically, to be cleansed of evils and falsities, and so to be reformed and regenerated, can be seen from the following passages:

When the Lord has washed away the filth of the daughters of Zion, and rinsed away the blood of Jerusalem... by the spirit of judgment and by the spirit of purification... (Isaiah 4:4)

Wash yourselves, make yourselves clean; put away the evil of your doings from My eyes. Cease to do evil... (Isaiah 1:16)

Wash your heart of its wickedness, O Jerusalem, that you may be saved. (Jeremiah 4:14)

Wash me clean of my iniquity..., and I shall be whiter than snow. (Psalms 51:2, 7)

...if you wash yourself with soda, and use much soap, your iniquity will still retain its spots. (Jeremiah 2:22)

If I wash myself with melted snow, and cleanse my hands with soap..., yet... my own clothes will abhor me. (Job 9:30-31)

Who... has washed his clothing in wine, and his vesture in the blood of grapes. (Genesis 49:11)

This is said of the celestial church, from which come people prompted by love toward the Lord, and in the highest sense it is said of the Lord Himself. Wine and the blood of grapes are spiritual and celestial Divine truth.

I washed you with water, and rinsed off your blood from upon you... (Ezekiel 16:9)

This is said of Jerusalem. Water is truth, and blood is an adulteration of truth.

[2] It can be seen from this what washing in the Israelite Church represented and thus symbolized. As, for example, that Aaron was to wash himself before he put on the vestments of his ministry (Leviticus 16:4, 24), and before he approached the altar to minister (Exodus 30:18-21; 40:30-31).

[3] It can be seen from this that among the children of Israel washing represented a spiritual washing, which is a cleansing from evils and falsities, and thus reformation and regeneration.

It is apparent also from the aforesaid what baptism by John in the Jordan symbolized (Matthew 3, Mark 1:4-13), and what the symbolic meaning of the following words by John regarding the Lord is, that He baptized with the Holy Spirit and with fire (Luke 3:16, John 1:33), and regarding himself, that he baptized with water (John 1:26). The meaning is that the Lord washes or purifies a person by Divine truth and Divine goodness, and that John by his baptism represented this. For the Holy Spirit is Divine truth, the fire is Divine goodness, and the water is representative of these. For water symbolizes the truth in the Word, which becomes goodness by one's living in accordance with it (no. 50).

376. Then one of the elders answered, saying to me, "Who are these arrayed in white robes, and where did they come from?" And I said to him, "Lord, you know." (7:13-14)

This symbolizes their desire to know and wish to inquire, and the reply and instruction given.

John was asked these questions because it is common in all Divine worship for a person to first wish, desire, and pray, and for the Lord then to reply, instruct, and effect. A person does not otherwise accept anything Divine.

Now because John saw those who were arrayed in white robes, and desired to know and ask who they were, and because this was perceived in heaven, therefore he was first asked about them, and afterward informed.

The case was similar with the prophet Zechariah when he saw the many representations displayed before him, as can be seen from Zechariah 1:9, 19, 21; 4:2, 5, 11-12; 5:2, 6, 10; 6:4.

Moreover in the Word we frequently read that the Lord answers when people call on Him or cry out to Him (as in Psalms 4:1; 17:6; 20:9; 34:4; 91:15; 120:1), and that He gives to people when they ask (Matthew 7:7-8; 21:22). Yet, even so, it is the Lord who gives people to ask and what they should ask for, and the Lord knows it, therefore, beforehand. But still it is the Lord's will that a person first ask, in order that the person may do so as though on his own, and that the petition may thus be assigned to him. Otherwise, if the petition itself did not emanate from the Lord, it would not have been said in those passages that people would receive whatever they ask.
