Deuteronomy 25:5
Jewish Publication Society 1917 · Berean Standard Bible
If brethren dwell together, and one of them die, and have no child, the wife of the dead shall not be married abroad unto one not of his kin; her husband’s brother shall go in unto her, and take her to him to wife, and perform the duty of a husband’s brother unto 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).
