1-я Царств 17:54

David is the man whom God now delights to honour, for he is a man after his own heart. We read in the foregoing chapter how, after he was anointed, Providence made him famous in the court; we read in this chapter how Providence made him much more famous in the camp, and, by both, not only marked him for a great man, but fitted him for the throne for which he was designed. In the court he was only Saul's physician; but in the camp Israel's champion; there he fairly fought, and beat Goliath of Gath. In the story observe, I. What a noble figure Goliath made, and how daringly he challenged the armies of Israel (Sa1 17:1-11). II. What a mean figure David made, when Providence brought him to the army (v. 12-30). III. The unparalleled bravery wherewith David undertook to encounter this Philistine (Sa1 17:31-39). IV. The pious resolution with which he attacked him (Sa1 17:40-47). V. The glorious victory he obtained over him with a sling and a stone, and the advantage which the Israelites thereby gained against the Philistines (Sa1 17:48-54). VI. The great notice which was hereupon taken of David at court (Sa1 17:55-58).

17:54 Jerusalem became an Israelite city later, when David captured it from the Jebusites (2 Sam 5:6-7). Jerusalem was probably the final destination of Goliath’s head, after David had become king. But David might have taken it to Jerusalem earlier to intimidate the non-Israelite occupants.
