Numbers 32:31

²⁹And Moses said to them, If the sons of Reuben and the sons of Gad will pass over Jordan with you, every one armed for war before the Lord, and ye shall subdue the land before you, then ye shall give to them the land of Gilead for a possession.

³⁰But if they will not pass over armed with you to war before the Lord, then shall ye cause to pass over their possessions and their wives and their cattle before you into the land of Canaan, and they shall inherit with you in the land of Canaan.

— Numbers 32:31 —

³²We will go over armed before the Lord into the land of Canaan, and ye shall give us our inheritance beyond Jordan.

³³And Moses gave to them, even to the sons of Gad and the sons of Reuben, and to the half tribe of Manasseh of the sons of Joseph, the kingdom of Sihon king of the Amorites, and the kingdom of Og king of Bashan, the land and its cities with its coasts, the cities of the land round about.
