Numbers 32:29-31

Darby Translation

²⁹ And Moses said unto them, If the children of Gad and the children of Reuben pass with you over the Jordan, every one armed for battle, before Jehovah, and the land be subdued before you, then ye shall give them the land of Gilead for a possession;

³⁰ but if they do not pass over with you armed, they shall have possessions among you in the land of Canaan.

³¹ And the children of Gad and the children of Reuben answered, saying, As Jehovah has said to thy servants, so will we do.
