Numbers 32:30

But if they will not pass over with you armed
Shall change their minds, and break their promise, and refuse to go over the river Jordan with the other tribes, and armed ready to engage in battle with the enemy:

they shall have possessions among you in the land of Canaan;
take their lot there, but have no inheritance or possessions on this side Jordan.
