Atad, otherwise Goren-ha-Atad, or Abel-mizraim
Archimandrite Nikifor’s Biblical Encyclopedia
(a place overgrown with thorny bramble — “the mourning of the Egyptians”) (Gen. 50:10, 11) — a place, probably located in the valley by the Jordan, in the land of Canaan, and placed by ancient writers between Jericho and the Jordan. Here was the threshing floor of Atad, and the name Goren-ha-Atad, or Abel-mizraim, arose from the circumstance that Joseph and his companions stopped here for seven days to mourn during their journey from Egypt to the land of Canaan, at the burial of Jacob (Gen. 50:10, 11).
