Jazer
Jazer is a town in the highlands east of the Jordan River, taken by Israel from the Amorites during the wilderness march and later assigned among the Levitical cities of refuge. A nearby body of water, the sea of Jazer, surfaces only once, in a Moabite oracle that mourns the loss of its vines.
Conquest from the Amorites
Jazer first appears as a target of Mosaic reconnaissance and then of conquest. "And Moses sent to spy out Jazer; and they took its towns, and the Amorites who were there were driven out" (Nu 21:32). The settled, walled character of the place is implicit in the language of "towns" surrounding the central site.
The well-watered country around Jazer drew the cattle-rich tribes of Reuben and Gad. "Now the sons of Reuben and the sons of Gad had a very great multitude of cattle: and when they saw the land of Jazer, and the land of Gilead, that, look, the place was a place for cattle" (Nu 32:1). Their petition to settle east of the Jordan names Jazer first in the cluster of conquered Amorite sites: "Ataroth, and Dibon, and Jazer, and Nimrah, and Heshbon, and Elealeh, and Sebam, and Nebo, and Beon" (Nu 32:3). When Gad rebuilds, Jazer is again among the towns named: "and Atrothshophan, and Jazer, and Jogbehah" (Nu 32:35).
Tribal Inheritance and Levitical City
In the allotment under Joshua, Jazer marks the edge of Gad's territory, fronting the Ammonite frontier. "And their border was Jazer, and all the cities of Gilead, and half the land of the sons of Ammon, to Aroer that is before Rabbah" (Jos 13:25). The town sits on the inland boundary, looking toward Rabbah of Ammon.
When the cities are distributed to the Levites, Jazer is set apart with its pasture lands. "Heshbon with its suburbs, Jazer with its suburbs; four cities in all" (Jos 21:39). The site thus passes from Amorite stronghold to tribal possession to a city given over to the priestly order.
The Sea of Jazer
The single reference to the sea of Jazer arises in the lament over Moab, where Sibmah's far-reaching vines are pictured stretching past Jazer's waters. "With more than the weeping of Jazer I will weep for you, O vine of Sibmah: your branches passed over the sea, they reached even to the sea of Jazer: on your summer fruits and on your vintage the destroyer has fallen" (Jer 48:32). The image binds Jazer to the vine country of Moab and to the grief that follows when the harvest is cut down.
Jazer in the Maccabean Campaigns
Jazer reappears in the eastern campaign of Judas Maccabeus, who breaks the resistance of the surrounding region and returns home with the captured town. "And he took Jazer and her towns, and returned into Judea" (1Ma 5:8). The phrase "her towns" echoes the same satellite pattern noted at the original conquest, indicating a settlement still organized around dependent villages centuries after Moses' day.
