2 And Saul taketh three thousand chosen men out of all Israel, and goeth to seek David and his men, on the front of the rocks of the wild goats, 3 and he cometh in unto folds of the flock, on the way, and there 'is' a cave, and Saul goeth in to cover his feet; and David and his men in the sides of the cave are abiding. 4 And the men of David say unto him, 'Lo, the day of which Jehovah said unto thee, Lo, I am giving thine enemy into thy hand, and thou hast done to him as it is good in thine eyes;' and David riseth and cutteth off the skirt of the upper robe which 'is' on Saul—gently. 5 And it cometh to pass afterwards that the heart of David smiteth him, because that he hath cut off the skirt which 'is' on Saul, 6 and he saith to his men, 'Far be it from me, by Jehovah; I do not do this thing to my lord—to the anointed of Jehovah—to put forth my hand against him, for the anointed of Jehovah he 'is'.'
Matthew Henry's Commentary on 1 Samuel 24:2-6
Commentary on 1 Samuel 24:1-7
(Read 1 Samuel 24:1-7)
God delivered Saul into David's hand. It was an opportunity given to David to exercise faith and patience. He had a promise of the kingdom, but no command to slay the king. He reasons strongly, both with himself and with his men, against doing Saul any hurt. Sin is a thing which it becomes us to startle at, and to resist temptations thereto. He not only would not do this bad thing himself, but he would not suffer those about him to do it. Thus he rendered good for evil, to him from whom he received evil for good; and was herein an example to all who are called Christians, not to be overcome of evil, but to overcome evil with good.
