Numbers 32:20-24

JPS_ASV_Byz(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 the Jordan before the LORD, until He hath driven out His enemies from before Him, 22 and the land be subdued before the LORD, and ye return afterward; then ye shall be clear before the LORD, and before 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 know ye your sin which will find you. 24 Build you cities for your little ones, and folds for your sheep; and do that which hath proceeded out of your mouth.'
