According to the Old Testament, the prophet Samuel anointed David to become king.
In 1 Samuel, God sends Samuel to Bethlehem, to the house of Jesse, after rejecting Saul’s dynasty. Jesse presents several sons, but God indicates that the youngest, David, is the chosen one. Samuel then anoints David in the presence of his brothers, and the biblical text says that the spirit of the Lord came upon David from that day onward.
David did not immediately take the throne. Saul remained king for a period, and David first became known as a musician, warrior, and leader. The anointing marks the beginning of his divine selection rather than the instant start of his reign.
Nathan was a later prophet associated with David’s court, while Elijah and Elisha belonged to a later period. Samuel also anointed Saul, making him a major figure in the transition from Israel’s judges to its monarchy.
