V.1-2 It seems hard to believe that Saul could be so determined to get rid of David, who was the one chosen by God instead of Saul (1 Sam. 15:1).
V.3-8 David’s men tell him to take the opportunity to kill Saul, but David refuses. He knows that Saul is still the king, even though he is acting so badly.
V.9-15 See the humble place that David takes. He calls himself a dead dog, a flea. He was quite right to honor king Saul, in spite of all the persecution that he had suffered. The day is coming when the Lord will have His rightful place. But in the meantime, He has told us to obey the authorities over us. On the other hand, the authority of God comes first, and we must never give up obedience to the Word of God, simply to obey the commandments of men.
V.16-22 Saul weeps when he hears the voice of David, and makes all kinds of confessions. We shall see whether he meant what he said.
