Charles Ellicott 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. —This makes an unnecessary transposition of a very involved sentence. The image is perfectly clear, though the syntax, as often happens in all languages, goes tripping itself up. The conqueror, after wading in the blood of his enemies, is met by the dogs, who lick his gory feet. With a change of one letter we may render, “That you may wash your foot in blood—indeed, the tongue of your dogs in (the blood of) your enemies.”
