Then he said to David: "You have been more honourable than I have, for you have rewarded me with good, and I have rewarded you with evil. Therefore may the Lord reward you good for what you have done to me this day."
And then he went on to tell David that he knew he would be king one day, and he earnestly begged him to be merciful to his father's house and not let his name perish out of the land.
So David promised him, before the Lord.
Then Saul went to his home, and David returned to his stronghold.
Saul later on again attempted to capture David, taking with him three thousand men.
David heard where Saul was camped, and taking Abishai with him, entered Saul's camp by night.
They found Saul asleep with his captain in a trench, with his men lying all around.
Abishai wished to kill Saul, but David refused, saying, "Destroy him not: for who can stretch out his hand against the Lord's anointed and be guiltless?"
So they took Saul's spear and water-bottle that was against his head and got away without anyone seeing them.
So David again spared the life of the man who for years had tried to kill him.
