Which king of Israel is known for killing Goliath?

The king of Israel known for killing Goliath is David. This event is a pivotal moment in the biblical narrative found in the First Book of Samuel. David, who was a young shepherd at the time, faced Goliath, a giant Philistine warrior, in a contest of champions. Armed only with his faith in God and a sling, David struck Goliath with a stone, ultimately leading to Goliath's defeat and death. This act not only showcased David's courage but also positioned him as a key figure in Israel's history, eventually leading to his ascension as king.

The other kings mentioned—Solomon, Rehoboam, and Jeroboam—played significant roles in the history of Israel but are not associated with the defeat of Goliath. Solomon is known for his wisdom and building the First Temple, Rehoboam is noted for his role in the division of the kingdom following Solomon's reign, and Jeroboam was the first king of the northern kingdom of Israel after the split. Each of their narratives is important, but none of them relates to the iconic battle between David and Goliath.
