Whose appearance was as lightning, and their garments glistening and white (Matt. 28:3; Mark 16:5; Luke 24:4; John 20:12, 13);

and those seen in heaven by John:

Who had garments of fine linen and white (Apoc. 4:4; 19:14).

And because intelligence is from Divine truth:

The garments of the Lord, when He was transfigured, were radiant and glistening white like the light (Matt. 17:2; Mark 9:3; Luke 9:29).

As light is Divine truth going forth from the Lord (see above, n. 129), so in the Word garments signify truths and intelligence from truths, as in the Apocalypse:

Those that have not defiled their garments shall walk with Me in white, for they are worthy. He that overcometh shall be clothed in white garments (3:4, 5);

Blessed is he that is awake and keepeth his garments (16:15).

And of Jerusalem, which means a church that is in truth,# 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. # "Jerusalem" signifies a church in which there is genuine doctrine (n. 402, 3654, 9166).
