Tur Gobel (Mount Ebal) - (Jabal Islamiyah) van www.christusrex.org
Eusebius, Onomasticon 64:9-15 (ca. 295 A.D.); Jerome 65:9-15 (ca. 390 A.D.)
Gebal (Deut 11:29), a mountain in the Promised Land, where an altar was built at Moses' command. And there are two mountains near Jericho, standing close and facing one another, one of which is called Gerizim and the other Gebal. However, the Samaritans believe these two mountains to be near Neapolis, but they are grossly mistaken, for the mountains they indicate are very far the one from the other, and the voice of anyone blessing or cursing from one of them, as the Scripture says, cannot be heard from the other.
Josephus, Antiquities 5.1.19 (1st cent. A.D.)
(68) The fifth year was not past, and there was not one of the Canaanites remained any longer, excepting some that had retired to places of great strength. So Joshua removed his camp to the mountainous country, and placed the tabernacle in the city of Shiloh, for that seemed a fit place for it, because of the beauty of its situation, until such time as their affairs would permit them to build a temple; (69) and from thence he went to Shechem, together with all the people, and raised an altar where Moses had beforehand directed; then did he divide the army, and place one half of them on Mount Gerizzim, and the other half on Mount Ebal, on which mountain the altar was;9 he also placed there the tribe of Levi, and the priests. (70) And when they had sacrificed, and denounced the [blessings and the] curses, and had left them engraven upon the altar, they returned to Shiloh.
