Charles Ellicott Commentary Psalms 54:7

"For he hath delivered me out of all trouble; And mine eye hath seen [my desire] upon mine enemies." — Psalms 54:7 (ASV)

This verse does not actually state what has happened, but, according to a well-known Hebrew idiom, should be rendered, When he shall have delivered, etc.

Has seen his desire. —Or, has gloated on. The Hebrews use the words seeing and looking very expressively, making the simple verb do almost what the eye itself can do: show hatred, love, triumph, defeat, wistfulness, disgust, etc. (Psalms 52:6; Psalms 59:10; Psalms 92:11; Song of Solomon 6:13; etc.)
