Numbers 34:10-15 - The Eastern Border Of The Land
10 And ye shall compass your east quarter from Hazarenan to Shepham. 11 And the coast shall go down from Shepham to Riblah on the east side of Ain. And then descend and go out at the side of the sea of Chinnereth eastward. 12 And then go down along by Jordan, and leave at the salt sea. And this shall be your land with all the coasts thereof round about.'"
13 And Moses commanded the children of Israel, saying, "This is the land which ye shall inherit by lot, and which the LORD commanded to give unto nine tribes and a half: 14 for the tribe of the children of Reuben have received, in the households of their fathers; and the tribe of the children of Gad in their fathers' households; and the half tribe of Manasseh, have received their inheritance - 15 that is, to wit, two tribes and a half have received their inheritance on the other side of Jordan by Jericho eastward, toward the sun-rising."
