John Gill Commentary Psalms 68:23

"That thou mayest crush [them], [dipping] thy foot in blood, That the tongue of thy dogs may have its portion from [thine] enemies." — Psalms 68:23 (ASV)

That your foot may be dipped in the blood of [your] enemies ,
&c.] This verse is in connection with (Psalms 68:21) , with (Psalms 68:23) being to be read in a parenthesis: the sense is, that the Messiah would so wound the head and hairy scalp of his people's enemies, and there should be such a large effusion of blood, that their feet should be dipped therein, (Revelation 14:20) ; (See Gill on Psalms 58:10);

[and] the tongue of your dogs in the same ;
who should lick it up, as the dogs licked the blood of Jezebel, (1 Kings 21:19) (2 Kings 9:35 2 Kings 9:36) ; and so such a carnage will be made of antichrist and his followers, that the fowls of the heavens will be called upon to eat the flesh of kings, captains, and mighty ones, (Revelation 19:17Revelation 19:18) .
