The LORD said to Moshe, If her father had but spit in her face, shouldn't she be ashamed seven days? let her be shut up outside of the camp seven days, and after that she shall be brought in again.
then his brother's wife shall come to him in the presence of the elders, and loose his shoe from off his foot, and spit in his face; and she shall answer and say, So shall it be done to the man who does not build up his brother's house.
