Numbers 32:22-32

22 and the land hath been subdued before Jehovah -- then afterwards ye do turn back, and have been acquitted by Jehovah, and by Israel; and this land hath been to you for a possession before Jehovah.
23 `And if ye do not so, lo, ye have sinned against Jehovah, and know ye your sin, that it doth find you;
24 build for yourselves cities for your infants, and folds for your flock, and that which is going out from your mouth do ye.'
25 And the sons of Gad and the sons of Reuben speak unto Moses, saying, `Thy servants do as my lord is commanding;
26 our infants, our wives, our cattle, and all our beasts, are there in cities of Gilead,
27 and thy servants pass over, every armed one of the host, before Jehovah, to battle, as my lord is saying.'
28 And Moses commandeth concerning them Eleazar the priest, and Joshua son of Nun, and the heads of the fathers of the tribes of the sons of Israel;
29 and Moses saith unto them, `If the sons of Gad and the sons of Reuben pass over with you the Jordan, every one armed for battle, before Jehovah, and the land hath been subdued before you, then ye have given to them the land of Gilead for a possession;
30 and if they do not pass over armed with you, then they have possessions in your midst in the land of Canaan.'
31 And the sons of Gad and the sons of Reuben answer, saying, `That which Jehovah hath spoken unto thy servants -- so we do;
32 we -- we pass over armed before Jehovah [to] the land of Canaan, and with us [is] the possession of our inheritance beyond the Jordan.'
