"When brothers dwell together and one of them dies and has no son, the wife of the deceased shall not become the wife of a {man of another family}; her brother-in-law {shall have sex with her}, and he shall take her {to himself} as wife, and he shall perform his duty as brother-in-law [with respect to] her.

But if the man [does] not want to take his sister-in-law, then his sister-in-law shall go up to the gate, to the elders, and she shall say, 'My brother-in-law refused {to perpetuate his brother's name} in Israel, [for] he is not willing {to marry me}.'

then she is to approach her brother-in-law in the presence of the elders, remove his sandal, spit in his face, and say in response, "May this be done to the man who does not preserve the lineage of his brother.'
