Deuteronomy 25:7-10

And if the man does not wish to take his brother’s wife, then his brother’s wife shall a go up to the gate to the elders and say, ‘My husband’s brother refuses to perpetuate his brother’s name in Israel; he will not perform the duty of a husband’s brother to me.’ Then the elders of his city shall call him and speak to him, and if he persists, saying, b ‘I do not wish to take her,’ then his brother’s wife shall go up to him in the presence of the elders and c pull his sandal off his foot and d spit in his face. And she shall answer and say, ‘So shall it be done to the man who does not e build up his brother’s house.’ 10 And the name of his house
Hebrew its name
shall be called in Israel, ‘The house of him who had his sandal pulled off.’
