In , which reports that Melchizedek, king of Salem and priest of El-Elyon (often translated “God Most High”), greeted Abraham with bread and wine and then blessed Abraham, Rendsburg saw the author of Genesis demonstrating the significance of Jerusalem. Rendsburg reported that virtually all scholars agree that Salem is short for Jerusalem. Abraham responded by giving Melchizedek a tenth of all he had — a priestly tithe. Then in , Abraham identified El-Elyon with YHVH. Rendsburg argued that a royal scribe in David's court included these verses to justify the continuation of the Jerusalemite priest Zadok as priest in Jerusalem after David took the city as his capital. The scribe, Rendsburg posited, was showing that David merely followed the precedent that the glorious ancestor Abraham set by tithing to a Canaanite priest in Jerusalem. Scholars have noticed that the account of David's life refers to two high priests — Abiathar and Zadok. Abiathar appears early in the narratives, for example in , even before David is king, but Zadok appears suddenly and only after David conquered Jerusalem. Rendsburg suggested that Zadok was probably the Canaanite high priest of Jerusalem, whom David permitted to continue to serve in that capacity. In that case, Zadok would also have been king of the city-state of Jerusalem. (Phoenician evidence shows that among the Canaanites, a single individual occupied both roles.) Rendsburg believed that Zadok should be identified with Araunah, who sold David the threshing floor to build an altar in . Rendsburg reported that the word "Araunah" was not a personal name but a title meaning “the Lord” (originally in Hurrian but in other Near Eastern languages as well); for example, calls him “Araunah the king.” More generally, Rendsburg concluded that royal scribes living in Jerusalem during the reigns of David and Solomon in the tenth century BCE were responsible for Genesis; their ultimate goal was to justify the monarchy in general, and the kingship of David and Solomon in particular; and Genesis thus appears as a piece of political propaganda.
