1 Samuel 17:54

to Jerusalem There are no indications that Jerusalem had yet attained any importance either as a political or religious centre. The citadel still remained in the hands of the Jebusites, though the lower city had been captured (Joshua 15:63). It seems best therefore to suppose that David deposited the head as a votive offering in the Tabernacle at Nobwhich was close to Jerusalem. We know that he afterwards placed Goliath's sword there, and possibly the rest of his armour along with it. This is preferable to the conjecture that the historian here relates by anticipation what David did eventually when he occupied Jerusalem.

in his tent So long as the army remained in the field he kept it as a trophy of his victory.

We might naturally expect that David would celebrate his victory by a Psalm of thanksgiving. No extant Psalm however can with certainty be referred to this occasion. The Sept. adds "against Goliath" to the title of Psalms 144 (Sept. 143), but without any sufficient probability; and the Psalm appended to the Psalter in the Sept., which professes to belong to this period, is certainly not authentic. A translation of it may be found in Smith's Dict. of the Bible, I. 403.
