For true and righteous are his judgments
As in (See Gill on Revelation 15:3), (See Gill on Revelation 16:7): this is to be understood of God's judgments in general, and is a reason of the attribution of praise and glory to him; which may be said to be true, because, being threatened, are now fulfilled; and to be "righteous", because according to the demerit of sin; and particularly God's judgments on antichrist are intended:
for he hath judged the great whore;
Jezebel, Babylon, the Romish antichrist, before spoken of, ( Revelation 17:1 ) not only by passing a sentence of condemnation on her, but by executing it, putting it into the hearts of the kings to hate and burn her, and utterly destroy her; and which is judging right, since it follows:
which did corrupt the earth with her
drew the kings and inhabitants of the Roman empire into wicked and idolatrous practices, and so corrupted and destroyed them in soul, body, and estate; (See Gill on Revelation 11:18) for this vision is contemporary with the seventh trumpet:
and hath avenged the blood of his servants at her
shed by her, ( Revelation 18:20 Revelation 18:24 ) ( 16:6 ) and this being done in righteous judgment, is matter of joy and praise to the saints.
