ha'-zor-ha-dat'-a (Aramaic chatsor chadhattah, "New Hazor"): "An Aramaic adjective, however, in this region is so strange that the reading must be questioned" (Di). One of the "uttermost cities .... of Judah toward the border of Edom" (Jos 15:25). Eusebius and Jerome describe a "New Hazor" to the East of Ascalon, but this is too far North.
