Parallel
Deuteronomy 25:5
World English Bible British Edition · Berean Standard Bible
If brothers dwell together, and one of them dies and has no son, the wife of the dead shall not be married outside to a stranger. Her husband’s brother shall go in to her, and take her as his wife, and perform the duty of a husband’s brother to her.
When brothers dwell together and one of them dies without a son, the widow must not marry outside the family. Her husband’s brother is to take her as his wife and fulfill the duty of a brother-in-law for her (note: Cited in Matthew 22:24, Mark 12:19, and Luke 20:28).
