The centurion replied, "Sir, I am not worthy to have you come under my roof. But just say the word, and my servant will be healed,

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.

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