“But the land shall be divided by lot. They shall receive their inheritance according to the names of the tribes of their fathers.

by the lot of their inheritance, as Yahweh commanded by the hand of Moses, for the nine tribes and the half-tribe.

“And when you divide by lot the land for inheritance, you shall offer a contribution to Yahweh, a holy portion of the land; the length shall be the length of 25,000 cubits, and the width shall be 20,000. It shall be holy within all its boundary round about.

“Therefore you will have no one stretching a measuring line For you by lot in the assembly of Yahweh.
