King Saul continues to harbour feelings of envy towards David so he and his soldiers continue to pursue him. But in the end, the king and his son, Jonathan, are killed in their battle against the Philistines. After their death, David becomes the king of Israel and rules them for thirty-three years. While ruling, King David captures the city of Jerusalem, once held by the Jebusites. King David, however, commits the sin of adultery with Bathsheba and the sin of pride with the census. But God is merciful and makes a promise to David that one from his line will reign as king forever and his kingdom will have no end.
