'Brother's' in the Bible

But if the man does not want to marry his brother's widow, then she must go to the elders at the town gate and say, "My husband's brother refuses to preserve his brother's name in Israel; he is unwilling to perform the duty of a brother-in-law to me!"

then his sister-in-law must approach him in view of the elders, remove his sandal from his foot, and spit in his face. She will then respond, "Thus may it be done to any man who does not maintain his brother's family line!"
