Numbers 32:28-30

32:28 So Moses gave orders about them to Eleazar the priest, to Joshua son of Nun, and to the heads of the families of the Israelite tribes. 32:29 Moses said to them: “If the Gadites and the Reubenites cross the Jordan with you, each one equipped for battle in the Lord’s presence, and you conquer the land, ¹  then you must allot them the territory of Gilead as their possession. 32:30 But if they do not cross over with you armed, they must receive possessions among you in Canaan.”

[32:29]  ¹ tn Heb “and the land is subdued before you.”
