6 And Moses said unto Aaron, and unto Eleazar and unto Ithamar, his sons, Let not the hair of your heads go loose, neither rend your clothes; that ye die not, and that he be not wroth with all the congregation: but let your brethren, the whole house of Israel, bewail the burning which Jehovah hath kindled.
