Deuteronomy 25:7-9 ▼

7 But if a man does not want to marry his brother’s wife, she shall go up to the elders at the gate and say, “My brother-in-law refuses to perpetuate his brother’s name in Israel and does not intend to perform his duty toward me.”

8 Thereupon the elders of his city shall summon him and speak to him. If he persists in saying, “I do not want to marry her,”

9 his sister-in-law, in the presence of the elders, shall go up to him and strip his sandal from his foot and spit in his face, declaring, “This is how one should be treated who will not build up his brother’s family!”
