A place on the south of Canaan
And your border shall turn from the south to the ascent of Akrabbim, and pass on to Zin: and the going forth thereof shall be from the south to Kadesh-barnea, and shall go on to Hazar-addar, and pass on to Azmon: And the border shall fetch a compass from Azmon unto the river of Egypt, and the goings out of it shall be at the sea. (Numbers 34:4-5)
From thence it passed toward Azmon, and went out unto the river of Egypt; and the goings out of that coast were at the sea: this shall be your south coast. (Joshua 15:4)
