Devarim 25:7-9

Orthodox Jewish Bible

⁷ And if the ish like not to take his brother’s isha, then let his brother’s isha go up to the sha’ar unto the zekenim, and say, My husband’s brother refuseth to raise up unto his brother a shem in Yisroel, he will not perform the levirate marriage with me.

⁸ Then the zekenim of his town 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 isha come unto him in the presence of the zekenim, and remove his sandal from off his foot, and spit in his face, and shall answer and say, So shall it be done unto that ish that will not build up the bais achiv (the house of his brother).
