Numbers 34:11

And the coast shall go down from Shepham to Riblah, on the east side of Ain; and the border shall descend, and shall reach unto the side of the sea of Chinnereth eastward:

The line traces part of the eastern boundary that Moses fixed for dividing the land among the tribes of Israel. That division embraced together both the territory already conquered and the territory still unsubdued. Each tribe was made responsible to subdue its own allotted inheritance. Levi was excluded from that tribal allotment because of its sanctuary service, receiving instead forty-eight cities scattered in different parts of the country.
