1 Samuel 19:4-6

New Catholic Bible

⁴ Jonathan spoke well of David to his father Saul. He said to him, “May the king not wrong his servant David, for he has not wronged you. What he has done has only been to your benefit. ⁵ He risked his life when he killed the Philistine. The Lord won a great victory for all of Israel. You saw it and you rejoiced. Why would you sin against innocent blood by killing David for no reason?”

⁶ Saul listened to Jonathan, and Saul swore, “As the Lord lives, he will not be killed.”
