Targum sobre Números 34:6

And for the western border you shall have the Great Ocean Sea; its limits are the waters of the beginning with the waters of old which are in its depth; its capes and havens, its creeks and its cities, its islands and ports, its ships and its recesses: this shall be your border westward.

And the (west) border shall be the Great Ocean Sea; its isles, ports, and ships, with the ancient waters that are in it, the waters of the beginning; this shall be your western border.
