Nob
Nob is a Benjamite town remembered above all as the priest-city of Ahimelech, the site at which David takes refuge during his flight from Saul, the place at which the resident priesthood is massacred by Doeg the Edomite, the post-exilic resettlement-site of returning Benjamites, and the final Assyrian stopover from which the conqueror shakes his hand at Jerusalem.
A Benjamite Town
Nob lies inside the Benjamite stretch of the post-exilic resettlement-roster of Nehemiah, alongside Anathoth and Ananiah: "at Anathoth, Nob, Ananiah" (Ne 11:32). The three-town entry sits in the from-Geba-onward Benjamite reoccupation-line introduced one verse earlier, fixing Nob as one of the named priest-region towns reoccupied after the return.
The City of the Priests
Nob is identified by an apposition that names what kind of town it is — "the city of the priests" (1Sa 22:19). The town is the residence of Ahimelech the son of Ahitub, who meets David at Nob trembling: "Then David came to Nob to Ahimelech the priest: and Ahimelech came to meet David trembling, and said to him, Why are you alone, and no man with you?" (1Sa 21:1). When Saul later moves to wipe out the Ahimelech priesthood, the summons goes specifically to "all his father's house, the priests who were in Nob" (1Sa 22:11), confirming that the entire priestly household is concentrated at this one site.
Tabernacle and Sword at Nob
Nob in Saul's reign holds the showbread and the ephod, which makes it the functional priestly center. When David asks for provisions, Ahimelech answers, "There is no common bread under my hand, but there is holy bread" (1Sa 21:4), and then "the priest gave him holy [bread]; for there was no bread there but the showbread, that was taken from before Yahweh" (1Sa 21:6). The sword of Goliath has also been kept at Nob: "The sword of Goliath the Philistine, whom you slew in the valley of Elah, look, it is here wrapped in a cloth behind the ephod" (1Sa 21:9). Showbread, ephod, and the trophy-sword of the Philistine champion are all at Ahimelech's hand at Nob.
The Massacre by Doeg
The visit to Nob is observed. Doeg the Edomite reports it to Saul: "I saw the son of Jesse coming to Nob, to Ahimelech the son of Ahitub" (1Sa 22:9). The report becomes the occasion for the slaughter of the Nob priesthood and the destruction of the town itself: "And Nob, the city of the priests, he struck with the edge of the sword, both men and women, children and sucklings, and oxen and donkeys and sheep, with the edge of the sword" (1Sa 22:19). The verse opens and closes with the same struck-with-the-edge-of-the-sword phrase, and the men-and-women / children-and-sucklings / oxen-and-donkeys-and-sheep catalogue measures the totality of the destruction inflicted on the priest-town after the eighty-five priests have already been killed.
The Assyrian Halt at Nob
Nob's last appearance is in Isaiah's oracle of the Assyrian advance, where the conqueror's march southward halts at Nob within sight of the capital: "This very day he will halt at Nob: he shakes his hand at the mount of the daughter of Zion, the hill of Jerusalem" (Isa 10:32). Nob is the final pause of the advance, close enough that the conqueror's gesture toward Mount Zion is a single hand-shake away from the city he intends to take.
