'Shoe' in the Bible

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 she shall answer and say, So shall it be done unto the man that doth not build up his brother's house.

And his name shall be called in Israel, The house of him that hath his shoe loosed.

And I have led you forty years in the wilderness: your clothes are not waxed old upon you, and thy shoe is not waxed old upon thy foot.
