Deu Deuteronomy, chapter Book of Deuteronomy, chapter 25
And if the man like not to take his brother’s wife, then let his brother’s wife go up to the gate unto the elders, and say, My husband’s brother refuses to raise up unto his brother a name in Yisra’el [He Holds Onto The Heel Of God], he will not perform the duty of my husband’s brother.Rut 4:4
