Deuteronomy 25:4-6

New International Reader's Version

⁴ Don’t stop an ox from eating while you use it to separate grain from straw.

⁵ Suppose two brothers are living near each other. And one of them dies without having a son. Then his widow must not marry anyone outside the family. Her husband’s brother should marry her. That’s what a brother-in-law is supposed to do. ⁶ Her first baby boy will be named after her first husband. Then the dead man’s name will continue in Israel.
