And the east border [was] the salt sea, [even] unto the end of Jordan,.... To the place where Jordan fell into it; so that this border was the whole length of the salt sea, which Josephus says was five hundred eighty furlongs; and, according to Pliny , an hundred miles:and [their] border in the north quarter [was] from the bay of the sea,at the uttermost part of Jordan; this northern border began where the eastern ended, at the bay or creek of the sea, where Jordan fell into it.
