When brethren dwell together and one of them die and have no child, the wife of the dead shall not be given out unto a stranger: but her brother-in-law shall go in unto her and take her to wife and marry her.

But and if the man will not take his sister-in-law, then let her go to the gate unto the elders and say, 'My brother-in-law refuseth to stir up unto his brother a name in Israel, he will not marry me.'

then let his sister-in-law go unto him in the presence of the elders and loose his shoe off his foot and spit in his face and answer and say, 'So shall it be done unto that man that will not build his brother's house.'
