Hazar-enan
Hazar-enan is the northeast boundary point of the promised land. It marks the eastern terminus of the northern border in the wilderness allotment under Moses, and reappears centuries later as the same fixed point in Ezekiel's vision of the restored land's tribal portions.
Northern boundary in the wilderness allotment
When the territory of Canaan is laid out for the tribes, Hazar-enan is the place where the northern border ends and the eastern border begins: "and the border will go forth to Ziphron, and the goings out of it will be at Hazar-enan: this will be your⁺ north border. And you⁺ will mark out your⁺ east border from Hazar-enan to Shepham" (Num 34:9-10). The same point serves as the corner where one boundary stops and the next starts.
Northern boundary in Ezekiel's restoration
Ezekiel returns to the same boundary in his vision of the future allotment. The northern line is described first: "And the border from the sea, will be Hazar-enon at the border of Damascus; and on the north northward is the border of Hamath. This is the north side" (Ezek 47:17). The placement is the same — at the border of Damascus, with Hamath beyond — though the form of the name is here written Hazar-enon.
The tribal apportionment that follows fixes the same point as the northern starting line for Dan: "Now these are the names of the tribes: From the north end, beside the way of Hethlon to the entrance of Hamath, Hazar-enan at the border of Damascus, northward beside Hamath (and they will have their sides east [and] west), Dan, one [portion]" (Ezek 48:1). The boundary point is unchanged across the texts: a fixed north-northeast marker at the edge of Damascus by which both the Mosaic allotment and Ezekiel's restored allotment are oriented.
