1 Samuel 19:1-6

1 And Saul spoke to Jonathan his son and to all his servants, that they should kill David. But Jonathan, Saul's son, delighted much in David.
2 And Jonathan told David, "Saul my father seeks to kill you; therefore take heed to yourself in the morning, stay in a secret place and hide yourself;
3 and I will go out and stand beside my father in the field where you are, and I will speak to my father about you; and if I learn anything I will tell you."
4 And Jonathan spoke well of David to Saul his father, and said to him, "Let not the king sin against his servant David; because he has not sinned against you, and because his deeds have been of good service to you;
5 for he took his life in his hand and he slew the Philistine, and the LORD wrought a great victory for all Israel. You saw it, and rejoiced; why then will you sin against innocent blood by killing David without cause?"
6 And Saul hearkened to the voice of Jonathan; Saul swore, "As the LORD lives, he shall not be put to death."
