Albert Barnes 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 - My earnest cry for deliverance from the designs of those who would betray me.

Give ear to the words of my mouth - Incline your ear to me, as one does who wishes to hear. See the notes at Psalms 17:6.
