After David killed the Philistine champion warrior, Goliath, Israel fell in love with its new hero.
King Saul did not. Not in the long haul. He eventually grew so jealous that he wanted to kill David.
But Saul's oldest son, Jonathan, was David's best friend. And he warned David when it was time to run. Here's the first part of the story, as it begins in 1 Samuel 19.
SAUL PLANS TO KILL DAVID
1Saul wanted to kill David. So he discussed it with his officials and with his son Jonathan, who was David’s good friend.2Jonathan told David. “My father Saul is looking for a way to kill you. Hide somewhere until tomorrow morning and stay alert.3I’ll take a walk with my father in the field and will try to talk him out of doing this to you. I’ll let you know what he says.”4Jonathan bragged up David to his father, King Saul. He said, “The king shouldn’t do anything wrong to David. He hasn’t done anything wrong to you. Everything he has done was to help you, not hurt you.5He risked his life when he fought the Philistine champion. The LORD gave Israel a huge victory that day. You saw it. You cheered it. So, why would you murder this innocent man?”6Saul took his son’s advice. And he promised, “As sure as the LORD lives, I’ll not kill David.”7Jonathan told David about it and then brought him to Saul. David resumed his duties for the king.
SAUL THROWS A SPEAR AT DAVID AGAIN
8War broke out again between Israel and the Philistines. David launched a crushing attack, and the Philistines ran away like before.9Then a dark and depressing spirit got the best of Saul. David played music to calm the king, who sat with a spear in his hand.10Saul threw the spear at David, who managed to dodge it. The spear lodged in the wall, and David left, escaping into the night.
MICHAL HELPS DAVID ESCAPE
11Saul sent guards to watch David’s house that night. Saul wanted to kill him in the morning. David’s wife Michal told her husband, “If you don’t get away from here tonight, you’ll be killed in the morning.”12Michal helped David escape down a high window. That’s how he got away.13Michal took the statue of an idol and put it in their bed. She covered it with David’s clothes and some blankets. And she topped the idol’s head with goat hair...
The story continues until Philistines kill Saul and most of his sons in a battle. Jonathan dies there, too (1 Samuel 31).
