What does 1 Samuel 26:22 mean?

Now therefore, please let my lord the king hear the words of his servant. If it is so that Yahweh has stirred you up against me, let him accept an offering. But if it is the children of men, they are cursed before Yahweh; for they have driven me out today that I shouldn’t cling to Yahweh’s inheritance, saying, ‘Go, serve other gods!’

Now therefore, don’t let my blood fall to the earth away from the presence of Yahweh; for the king of Israel has come out to seek a flea, as when one hunts a partridge in the mountains.”

Then Saul said, “I have sinned. Return, my son David; for I will no more do you harm, because my life was precious in your eyes today. Behold, I have played the fool, and have erred exceedingly.”

Yahweh will render to every man his righteousness and his faithfulness; because Yahweh delivered you into my hand today, and I wouldn’t stretch out my hand against Yahweh’s anointed.

Behold, as your life was respected today in my eyes, so let my life be respected in Yahweh’s eyes, and let him deliver me out of all oppression.”

Then Saul said to David, “You are blessed, my son David. You will both do mightily, and will surely prevail.” So David went his way, and Saul returned to his place.
