C. F. Keil and Franz Delitzsch on 1 Samuel 24:11

1Sa 24:11

To confirm what he said, he then showed him the lappet of his coat which he had cut off, and said, “My father, see.” In these words there is an expression of the childlike reverence and affection which David cherished towards the anointed of the Lord. “For that I cut off the lappet and did not kill thee, learn and see (from this) that (there is) not evil in my hand (i.e., that I do not go about for the purpose of injury and crime), and that I have not sinned against thee, as thou nevertheless layest wait for my soul to destroy it.”
