Mark 12:19

⁵If 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. ⁶It 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.

⁷If 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.” ⁸Then the elders of his city shall call him, and speak to him. If he stands and says, “I don’t want to take her,” ⁹then his brother’s wife shall come to him in the presence of the elders, and loose his sandal from off his foot, and spit in his face. She shall answer and say, “So shall it be done to the man who does not build up his brother’s house.” ¹⁰His name shall be called in Israel, “The house of him who had his sandal removed.”

⁵Then Boaz said, “On the day you buy the field from the hand of Naomi, you must buy it also from Ruth the Moabitess, the wife of the dead, to raise up the name of the dead on his inheritance.”

⁸Judah said to Onan, “Go in to your brother’s wife, and perform the duty of a husband’s brother to her, and raise up offspring for your brother.”

¹¹Naomi said, “Go back, my daughters. Why do you want to go with me? Do I still have sons in my womb, that they may be your husbands? ¹²Go back, my daughters, go your way; for I am too old to have a husband. If I should say, ‘I have hope,’ if I should even have a husband tonight, and should also bear sons, ¹³would you then wait until they were grown? Would you then refrain from having husbands? No, my daughters, for it grieves me seriously for your sakes, for the LORD’s hand has gone out against me.”
