John Gill Commentary Psalms 142:6

"Attend unto my cry; For I am brought very low: Deliver me from my persecutors; For they are stronger than I." — Psalms 142:6 (ASV)

Attend to my cry
His prayer and supplication for help in his distress, which he desires might be listened to and answered;

for I am brought very low ;
in his spirit, in the exercise of grace, being in great affliction, and reduced to the utmost extremity, weakened, impoverished, and exhausted; wanting both men and money to assist him, (Psalms 79:8) (116:6) ;

deliver me from my persecutors ;
Saul and his men, who were in pursuit of him with great warmth and eagerness;

for they are stronger than I ;
more in number, and greater in strength; Saul had with him three thousand chosen men out of all Israel, ablebodied men, and expert in war; veteran troops, and in high spirits, with their king at the head of them; David had about six hundred men, and these poor mean creatures, such as were in distress, in debt, and discontented, and in want of provisions, and dispirited; see (1 Samuel 22:2) (23:13) (24:2) (Psalms 18:16) .

So the spiritual enemies of the Lord's people are stronger than they, (Jeremiah 31:11) (Ephesians 6:12) .
