⁴ “You shall not muzzle the ox while he is threshing [to prevent him from eating any of the grain].^(A)

⁵ “If brothers are living together and one of them dies without a son, the widow of the deceased shall not be married outside the family to a stranger. Her husband’s brother shall be intimate with her after taking her as his wife and perform the duty of a husband’s brother to her.
