Deuteronomy 25:6-7 ▼

6 It shall be that the firstborn whom she bears shall succeed in the name of his brother who is dead, that his name not be blotted out of Israel.

7 If the man doesn’t want to take his brother’s wife, then his brother’s wife shall go up to the gate to the elders, and say, “My husband’s brother refuses to raise up to his brother a name in Israel. He will not perform the duty of a husband’s brother to me.”
