Psalm 130:2

Lord, hear my voice
His prayer, which was vocal: God is a God hearing prayer; sometimes his people think he does not hear them; but he always does, and in his own time answers; for to hear prayer with him is to answer it; which he does likewise in his own way as well as time; and not always in the way and at the time his people would have him;

let thine ears be attentive to the voice of my supplications;
his prayers put up in an humble suppliant manner, for grace and mercy; not pleading merit and righteousness: these he desires God would hearken to and hear, listen unto, bow and incline his ears, as he is sometimes said to do; which is a wonderful instance of his condescension.
