Saul was the first king of the Israelite nation. Samuel, the prophet, had anointed him as the king. Saul had won many battles against the enemies of God's people. But God wasn't happy with Saul as king, because he disobeyed His commands.
Samuel went to Saul. He said, "Since you have disobeyed the Lord's commands, God does not want you as king." God told Samuel to go to Bethlehem to find a name named Jesse. God said he had chosen one of Jesse's sons to be the next king.
So Samuel went to Bethlehem to see Jesse and his sons. Samuel looked at the oldest son. He thought he looked like he would be a good king, but the Lord said, "I do not look at the outward appearance of a man. I look at his heart. This is not the son that will be king."
Then Jesse called his next son and had him pass in front of Samuel. He was not the one the Lord had chosen either. Seven of Jesse's sons passed before Samuel, but not one of them was chosen by God.
Samuel asked, "Are these all the sons you have?" Jesse said, "No, there is still the youngest son, David. He is out tending sheep." Samuel sent someone to get David. When David came in, Samuel could see that he was very strong and healthy. When David arrived, the Lord said to Samuel, "This is the one. Anoint him as king." So Samuel took the oil and anointed David in front of his brothers. Immediately, the Spirit of the Lord was with David.
Later, David would fight and kill Goliath, the giant Philistine. He would also grow up to become Israel's greatest king.
And Jesus would be born into David's family many years later! As king, David wrote many of the Psalms. God loved David.
