'Sandal' in the Bible

He kept proclaiming, "The one who is coming after me is stronger than I am, and I am not worthy to bend down and untie his sandal straps.

John replied to all of them, "I'm baptizing you with water, but one is coming who is more powerful than I, and I'm not worthy to untie his sandal straps. It is he who will baptize you with the Holy Spirit and fire.

the one who is coming after me, whose sandal straps I am not worthy to untie."
