John Gill Commentary Psalms 54:2

"Hear my prayer, O God; Give ear to the words of my mouth." — Psalms 54:2 (ASV)

Hear my prayer, O God
The psalmist first puts up his petitions, and then desires to be heard; his distress, and the fervency of his spirit, not suffering him to observe order;

give ear to the words of my mouth ;
for the prayer which was conceived in his mind, and inwrought there by the Spirit of God, was expressed vocally.
