Deuteronomy 25:9

then his brother’s wife shall go up to him in the presence of the elders and pull his sandal 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.’

his brother’s widow shall go up to him in the presence of the elders, take off one of his sandals, spit in his face and say, “This is what is done to the man who will not build up his brother’s family line.”

then his sister-in-law will go up to him in the sight of the elders, remove his sandal from his foot, and spit in his face. Then she will declare, ‘This is what is done to a man who will not build up his brother’s house.’

the widow must walk over to him in the presence of the elders, pull his sandal from his foot, and spit in his face. Then she must declare, ‘This is what happens to a man who refuses to provide his brother with children.’

then his sister-in-law shall go near him before the eyes of the elders, and she shall pull off his sandal from his foot, and she shall spit in his face, and she shall declare and she shall say, ‘This is how it is done to the man who does not build the house of his brother.’

Then shall his brother’s wife come unto him in the presence of the elders, and loose his shoe from off his foot, and spit in his face, and shall answer and say, So shall it be done unto that man that will not build up his brother’s house.
