Jonathan’s Intervention
1 Samuel 19: 1-7
1Sa 19:1 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.
1Sa 19:2 And Jonathan told David, “Saul my father seeks to kill you. Therefore be on your guard in the morning. Stay in a secret place and hide yourself.
1Sa 19:3 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.”
1Sa 19:4 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 brought good to you.
1Sa 19:5 For he took his life in his hand and he struck down the Philistine, and the LORD worked a great salvation for all Israel. You saw it, and rejoiced. Why then will you sin against innocent blood by killing David without cause?”
1Sa 19:6 And Saul listened to the voice of Jonathan. Saul swore, “As the LORD lives, he shall not be put to death.”
1Sa 19:7 And Jonathan called David, and Jonathan reported to him all these things. And Jonathan brought David to Saul, and he was in his presence as before.
