Genesis 42:22 - Exposition

And Reuben —who had not consented to, but had been altogether unable to prevent, the wickedness of his brethren ( Genesis 37:22 , Genesis 37:29 )— answered them, saying, Spake I not unto you, saying, Do not sin against the child (or lad); and ye would not hear? therefore, behold, also his blood is required —literally, and also his blood, behold it is required . This was in accordance with the Noachic law against bloodshed ( Genesis 9:5 ), with which it is apparent that Jacob's sons were acquainted.
