Prophet Samual brought David to King Saul's court
A battle with the Philistines took place and alone David defeated the Giant Goliath with a slingshot.David won many more battles and Saul grew jealous of him. Saul planned to kill David, so David fled.
After David left, another battle with the Philistines took place. King Saul and his heir were killed.
After this battle, David became king. He conquered Jerusalem and soon had all of the regions in Canaan under his control.David wanted to build God a home, but God said this was not nessessary. God built a home for David and told him that it would be up to David's offspring to build God a home.
One of David's guards had a wife called Bathsheba. David got Bathsheba pregnant and had the Guard executed. David felt very guilty after this and repented. God forgave David, but David's kingdom collapses.
David's son assaults David's daughter and his other son kills this son for what he did. This son then takes the throne from David but dies. So David gets the throne back but he is a broken man now.
