Deuteronomy 25:4-6

The Message

⁴ Don’t muzzle an ox while it is threshing.

^5-6 When brothers are living together and one of them dies without having had a son, the widow of the dead brother shall not marry a stranger from outside the family; her husband’s brother is to come to her and marry her and do the brother-in-law’s duty by her. The first son that she bears shall be named after her dead husband so his name won’t die out in Israel.
