Deuteronomy 25:8-10

Amplified Bible

⁸ Then the elders of his city will summon him and speak to him. And if he stands firm and says, ‘I do not want to marry her,’ ⁹ then his brother’s widow shall approach him in the presence of the elders, and pull his sandal off his foot and spit in his face; and she shall answer and say, ‘So it is done to that man who does not build up his brother’s household.’ ¹⁰ In Israel his [family] name shall be, ‘The house of him whose sandal was removed.’
