And the armies which were in heaven followed him upon white horses, clothed in fine linen, white and clean.
The armies ... in heaven - (cf. Revelation 14:20.) The glorified saints whom God "will bring with" Christ at His advent: both the living transfigured, and those raised and meeting the Lord in the air (1 Thessalonians 4:1-18: cf. Revelation 17:14); also "His mighty angels" (2 Thessalonians 1:7).
White and (so 'Aleph (') Origen, Andreas) clean - `pure.' A B, Vulgate, Syriac, Cyprian, omit "and."
