Thomas Aquinas, on Isa 59:19

“And they from the west, shall fear the name of the Lord: and they from the rising of the sun, his glory: when he shall come as a violent stream, which the spirit of the Lord driveth on:”

“1047. Second, he sets out the minister of salvation or vengeance: when he shall come as a violent stream, because of the magnitude of his power and strength, or Christ, the minister: the stream of the river makes the city of God joyful (Ps 45:5[46:4]). 1050. Note also on the words, as a violent stream (Isa 59:19), that Christ is a violent stream: first, because of the multitude of water: the river of God is filled with water (Ps 64:10[65:9]); second, because of the fervor of love: a swift stream of fire issued forth from before him (Dan 7:10); third, because of the swiftness of its course: the stream of the river makes the city of God joyful (Ps 45:5[46:4]); fourth, because of the height of its source: and he showed me a river of water of life, clear as crystal, proceeding from the throne of God and of the lamb (Rev 22:1).”
