Numbers 32:20-28

20 So a Moses said to them, “If you will do this, if you will take up arms to go before the  Lord for the war, 21 and every armed man of you will pass over the Jordan before the  Lord, until he has b driven out his enemies from before him 22 and the land is subdued before the  Lord; then after that you shall return and be free of obligation to the  Lord and to Israel, and c this land shall be your possession before the  Lord. 23 But if you will not do so, behold, you have sinned against the  Lord, and d be sure your sin will find you out. 24  e Build cities for your little ones and folds for your sheep, and do what you have promised.” 25 And the people of Gad and the people of Reuben said to Moses, “Your servants will do as my lord commands. 26  f Our little ones, our wives, our livestock, and all our cattle shall remain there in the cities of Gilead, 27  g but your servants will pass over, every man who is h armed for war, before the  Lord to battle, as my lord orders.”

28 So i Moses gave command concerning them to Eleazar the priest and to j Joshua the son of Nun and to the heads of the fathers’ houses of the tribes of the people of Israel.
