Numbers 32:25-28 New King James Version (NKJV)

25. And the children of Gad and the children of Reuben spoke to Moses, saying: “Your servants will do as my lord commands.

26. Our little ones, our wives, our flocks, and all our livestock will be there in the cities of Gilead;

27. but your servants will cross over, every man armed for war, before the Lord to battle, just as my lord says.”

28. So Moses gave command concerning them to Eleazar the priest, to Joshua the son of Nun, and to the chief fathers of the tribes of the children of Israel.
