Numbers 34:5-8

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. And as for the western border, ye shall even have the great sea for a border: this shall be your west border. And this shall be your north border: from the great sea ye shall point out for you mount Hor: from mount Hor ye shall point out your border unto the entrance of Hamath; and the goings forth of the border shall be to Zedad
