For, lo, they lie in wait for my soul - They lie in wait as wild beasts do for their prey, ready to spring upon it. The word used here is often employed to denote the act of lying in ambush; of watching in secret places to spring upon a victim: Judges 9:32; Judges 21:20; Psalms 10:9. The word “soul” here means “life.” They lie in ambush that they may kill me.
The mighty are gathered against me - Strong men; hostile men; cruel men. Saul would employ on this occasion not the weak, the cowardly, the faint-hearted, but men of courage and strength; men who were unscrupulous in their character; men who would not be likely to be moved by entreaty, or turned from their purpose by compassion. It is not mere “strength” that is here referred to, but that kind of strength or courage which can be employed in a desperate enterprise, and which is suited to accomplish any scheme of wickedness, however daring or difficult.
Not for my transgression, nor for my sin - This is done not on account of my violating the laws of the land, nor because it is alleged that I am a sinner against God. David was conscious that he did not deserve this treatment from the hand of man. He bad been guilty of no wrong against Saul that exposed him to just punishment. He carried with him the consciousness of innocence as to any crime that could have made this treatment proper; and he felt that it was all the result of unjust suspicions. It was not improper for him to refer to this in his prayer; for, however he might feel that he was a sinner in the sight of God, yet he felt that a great and grievous wrong was done him by man; and he prayed, therefore, that a righteous God would interpose. See Psalms 7:8, note; Psalms 17:2, note; Psalms 35:24, note; Psalms 43:1, note.
