Deuteronomy 25:8-10

King James Version

⁸ Then the elders of his city shall call him, and speak unto him: and if he stand to it, and say, I like not to take her;

⁹ Then shall his brother's wife come unto him in the presence of the elders, and loose his shoe from off his foot, and spit in his face, and shall answer and say, So shall it be done unto that man that will not build up his brother's house.

¹⁰ And his name shall be called in Israel, The house of him that hath his shoe loosed.
