1 Samuel 19:4-6

Amplified Bible, Classic Edition

⁴ And Jonathan spoke well of David to Saul his father and said to him, Let not the king sin against his servant David, for he has not sinned against you, and his deeds have been of good service to you.

⁵ For he took his life in his hands and slew the Philistine, and the Lord wrought a great deliverance for all Israel; you saw it and rejoiced. Why then will you sin against innocent blood and kill David without a cause?

⁶ Saul heeded Jonathan and swore, As the Lord lives, David shall not be slain.
