Numbers

And the children of Reuben, and the children of Gad, and half the tribe of Manasseh, passed over armed before the children of Israel, as Moses spake unto them:

About forty thousand prepared for war passed over before the Lord unto battle, to the plains of Jericho.

Until the Lord have given your brethren rest, as he hath given you, and they also have possessed the land which the Lord your God giveth them: then ye shall return unto the land of your possession, and enjoy it, which Moses the Lord’s servant gave you on this side Jordan toward the sunrising.

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

We will pass over armed before the Lord into the land of Canaan, that the possession of our inheritance on this side Jordan may be ours.
