The Hebrews who had earlier gone over to the Philistine side joined the Israelites who were with Saul and Jonathan.

Saul said, “Let’s go down after the Philistines at night; we will rout them until the break of day. We won’t leave any of them alive!” They replied, “Do whatever seems best to you.” But the priest said, “Let’s approach God here.”

After Saul had secured his royal position over Israel, he fought against all their enemies on all sides – the Moabites, Ammonites, Edomites, the kings of Zobah, and the Philistines. In every direction that he turned he was victorious.

Goliath stood and called to Israel’s troops, “Why do you come out to prepare for battle? Am I not the Philistine, and are you not the servants of Saul? Choose for yourselves a man so he may come down to me!

But Saul replied to David, “You aren’t able to go against this Philistine and fight him! You’re just a boy! He has been a warrior from his youth!”

David went on to say, “The Lord who delivered me from the lion and the bear will also deliver me from the hand of this Philistine!” Then Saul said to David, “Go! The Lord will be with you.”

He took his staff in his hand, picked out five smooth stones from the stream, placed them in the pouch of his shepherd’s bag, took his sling in hand, and approached the Philistine.

But David replied to the Philistine, “You are coming against me with sword and spear and javelin. But I am coming against you in the name of the Lord of hosts, the God of Israel’s armies, whom you have defied!

This very day the Lord will deliver you into my hand! I will strike you down and cut off your head. This day I will give the corpses of the Philistine army to the birds of the sky and the wild animals of the land. Then all the land will realize that Israel has a God

David reached his hand into the bag and took out a stone. He slung it, striking the Philistine on the forehead. The stone sank deeply into his forehead, and he fell down with his face to the ground.

Now as Saul watched David going out to fight the Philistine, he asked Abner, the general in command of the army, “Whose son is this young man, Abner?” Abner replied, “As surely as you live, O king, I don’t know.”

When the men arrived after David returned from striking down the Philistine, the women from all the cities of Israel came out singing and dancing to meet King Saul. They were happy as they played their tambourines and three-stringed instruments.

Then Saul said to David, “Here’s my oldest daughter, Merab. I want to give her to you in marriage. Only be a brave warrior for me and fight the battles of the Lord.” For Saul thought, “There’s no need for me to raise my hand against him. Let it be the hand of the Philistines!”

Saul said, “I will give her to him so that she may become a snare to him and the hand of the Philistines may be against him.” So Saul said to David, “Today is the second time for you to become my son-in-law.”

when David, along with his men, went out and struck down two hundred Philistine men. David brought their foreskins and presented all of them to the king so he could become the king’s son-in-law. Saul then gave him his daughter Michal in marriage.

He risked his life when he struck down the Philistine and the Lord gave all Israel a great victory. When you saw it, you were happy. So why would you sin against innocent blood by putting David to death for no reason?”

So David and his men went to Keilah and fought the Philistines. He took away their cattle and thoroughly defeated them. David delivered the inhabitants of Keilah.

David thought to himself, “One of these days I’m going to be swept away by the hand of Saul! There is nothing better for me than to escape to the land of the Philistines. Then Saul will despair of searching for me through all the territory of Israel and I will escape from his hand.”

Neither man nor woman would David leave alive so as to bring them back to Gath. He was thinking, “This way they can’t tell on us, saying, ‘This is what David did.’” Such was his practice the entire time that he lived in the country of the Philistines.

In those days the Philistines gathered their troops for war in order to fight Israel. Achish said to David, “You should fully understand that you and your men must go with me into the battle.”
