Argob
Argob is a trans-Jordan region inside the Bashan kingdom of Og, captured by Israel under Moses and assigned to the half-tribe of Manasseh. It is a fortified-city country — sixty walled towns with bars and gates — bordered on the north by the Geshurites and Maacathites and renamed Havvoth-jair after the Manassite captain who took it. Centuries later, when Pekah son of Remaliah strikes down king Pekahiah inside the royal house in Samaria, "Argob" surfaces a second time as the personal name of one of the conspirator's confederates.
The Region in Og's Kingdom
Argob first appears as the heart of the Bashan kingdom Israel takes from Og. The conquest tally is comprehensive: "we took all his cities at that time; there was not a city which we did not take from them; threescore cities, all the region of Argob, the kingdom of Og in Bashan" (De 3:4). The cities themselves are the regional signature — fortified strongholds set apart from a separate class of unwalled towns: "All these were cities fortified with high walls, gates, and bars; besides the unwalled towns a great many" (De 3:5). The wider summary of the Transjordan campaign describes Bashan reaching "to Salecah and Edrei, cities of the kingdom of Og in Bashan" (De 3:10), and Argob is the name attached to the densest cluster of those fortified seats.
Inheritance of the Half-Tribe of Manasseh
When Moses parcels out the conquered land east of the Jordan, Argob goes to the half-tribe of Manasseh together with the rest of Bashan: "the rest of Gilead, and all Bashan, the kingdom of Og, I gave to the half-tribe of Manasseh; all the region of Argob, even all Bashan. (The same is called the land of Rephaim" (De 3:13). The verse equates the region of Argob with all Bashan and identifies the same territory as the older "land of Rephaim," locating the Manassite holding inside an even more ancient geographic memory.
Jair's Renaming — Havvoth-jair
The northern frontier of Argob is set by the Geshurite and Maacathite peoples, and the region itself takes a new personal-name from its Manassite conqueror: "Jair the son of Manasseh took all the region of Argob, to the border of the Geshurites and the Maacathites, and called them, even Bashan, after his own name, Havvoth-jair, to this day" (De 3:14). The verb "took" carries Jair as subject and the whole Argob region as object; the border-clause names the Geshurites and Maacathites as the frontier peoples; the call-verb stamps the Bashan country with Jair's name as Havvoth-jair, with a "to this day" durability that fixes the personal name on the territory after his lifetime.
Argob in Solomon's Administrative System
The region remains a recognizable administrative unit into the united monarchy. Among Solomon's twelve provisioning officers, Ben-geber is stationed at Ramoth-gilead, and his portfolio includes both the Jair-towns of Gilead and the Argob district: "Ben-geber, in Ramoth-gilead (to him [pertained] the towns of Jair the son of Manasseh, which are in Gilead; [even] to him [pertained] the region of Argob, which is in Bashan, threescore great cities with walls and bronze bars)" (1Ki 4:13). The threescore-city count and the walled-and-barred description match the De 3:4-5 conquest-era picture; centuries on, Argob is still being counted as a sixty-city walled district within Bashan and is now feeding Solomon's court for its share of the royal year.
Argob the Confederate of Pekah
In the closing decades of the northern kingdom, the name "Argob" reappears in a different register — as a person, attached to the coup that ends Pekahiah's reign. Pekahiah son of Menahem reigns two years in Samaria, "And Pekah the son of Remaliah, his captain, conspired against him, and struck him in Samaria, in the castle of the king's house, with Argob and Arieh; and with him were fifty men of the Gileadites: and he slew him, and reigned in his stead" (2Ki 15:25; the same conspiracy is rehearsed in the Pekahiah annal at 2Ki 15:22). The text places Argob and Arieh alongside Pekah inside the royal stronghold and counts them with a fifty-man Gileadite force; whether the name carries any link back to the trans-Jordan region, the narrative does not say. Pekah's twenty-year reign that follows runs under the verdict that he "did not depart from the sins of Jeroboam the son of Nebat" and ends with the first Assyrian deportation of the Galilean north under Tiglath-pileser, before Hoshea the son of Elah strikes him down in turn.
