Ulangan 25:9

maka janda itu harus mendekati dia di hadapan para pemimpin, melepaskan salah satu alas kakinya, meludahi mukanya, dan berkata, ‘Beginilah yang dilakukan kepada laki-laki yang tidak mau melanjutkan keturunan bagi almarhum saudaranya.’

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.
