Saul

Saul was the first king of the Israelite nation.After the people of Israel demanded that Samuel find them a king,God revealed Saul to Samuel as the one who He wanted to be king of Israel.He was anointed by Samuel.Later,Saul leads the Israelites into battle against the Ammonites and the Israelites come out victorious.Soon after this the Israelite nation finds itself at war with the Philistines.Yet,during the preparation for war,he got impatient waiting for Samuel to come and make a sacrifice to the Lord,so he offered it himself.Because of this,Samuel said that his reign would not endure.So,the Israelites entered a state of almost constant warfare with the Philistines.
Saul is soon threatened by the anointing of a future king of Israel,the man to take his place.Samuel anointed David,and so when David started to become even more popular among the people Saul determined to kill him.Fortunately,Saul never is able to actually kill him.In the end,Saul was wounded in battle and committed suicide by falling on his sword.
