Blessed is he that is awake and keepeth his garments
(16:15).
And of Jerusalem, which means a church that is in truth,{1} it is written in Isaiah:
Awake, put on thy strength, O Zion; put on the garments of
thy beauty, O Jerusalem (52:1).
And in Ezekiel:
Jerusalem, I girded thee about with fine linen, and covered thee with silk. Thy garments were of fine linen and silk (16:10, 13);
besides many other passages. But he who is not in truths is said "not to be clothed with a wedding garment," as in Matthew:
When the king came in he saw a man that had not on a wedding garment; and he said unto him, Friend, how camest thou in hither not having a wedding garment? Wherefore he was cast out into the outer darkness (22:11-13).
The house of the wedding feast means heaven and the church because of the conjunction of the Lord with heaven and the church by means of His Divine truth; and for this reason the Lord is called in the Word the Bridegroom and Husband; and heaven, with the church, is called the bride and the wife.
{Footnote 1} "Jerusalem" signifies a church in which there is genuine doctrine (n. 402, 3654, 9166).
181. That the garments of angels do not merely appear as garments, but are real garments, is evident from the fact that angels both see them and feel them, that they have many garments, and that they put them off and put them on, that they care for those that are not in use, and put them on again when they need them. That they are clothed with a variety of garments I have seen a thousand times. When I asked where they got their garments, they said from the Lord, and that they receive them as gifts, and sometimes they are clothed with them unconsciously. They said also that their garments are changed in accordance with their changes of state, that in the first and second state their garments are shining and glistening white, and in the third and fourth state a little less bright; and this likewise from correspondence, because their changes of state have respect to intelligence and wisdom (of which see above, n. 154, 161).
