'Sandal' in the Bible

of whom I am not worthy that I may loose the cord of his sandal.'

and the Lord said to him, Loose the sandal of thy feet, for the place in which thou hast stood is holy ground;

and as John was fulfilling the course, he said, Whom me do ye suppose to be? I am not he, but, lo, he doth come after me, of whom I am not worthy to loose the sandal of his feet.
