Numbers 32:20-23

ERV(i) 20 And Moses said unto them, If ye will do this thing; If ye will arm yourselves to go before the LORD to the war, 21 and every armed man of you will pass over Jordan before the LORD, until he hath driven out his enemies from before him, 22 and the land be subdued before the LORD: then afterward ye shall return, and be guiltless towards the LORD, and towards Israel; and this land shall be unto you for a possession before the LORD. 23 But if ye will not do so, behold, ye have sinned against the LORD: and be sure your sin will find you out.
