Deuteronomy 25:5-10

⁵ 'When brethren dwell together, and one of them hath died, and hath no son, the wife of the dead is not without to a strange man; her husband's brother doth go in unto her, and hath taken her to him for a wife, and doth perform the duty of her husband's brother; ⁶ and it hath been, the first-born which she beareth doth rise for the name of his dead brother, and his name is not wiped away out of Israel. ⁷ 'And if the man doth not delight to take his brother's wife, then hath his brother's wife gone up to the gate, unto the elders, and said, My husband's brother is refusing to raise up to his brother a name in Israel; he hath not been willing to perform the duty of my husband's brother; ⁸ and the elders of his city have called for him, and spoken unto him, and he hath stood and said, I have no desire to take her; ⁹ 'Then hath his brother's wife drawn nigh unto him, before the eyes of the elders, and drawn his shoe from off his foot, and spat in his face, and answered and said, Thus it is done to the man who doth not build up the house of his brother; ¹⁰ and his name hath been called in Israel—The house of him whose shoe is drawn off.
