'Sandals' in the Bible

John answered them all by saying, “As for me, I baptize you [only] with water; but One who is mightier [more powerful, more noble] than I is coming, and I am not fit to untie the strap of His sandals [even as His slave]. He will baptize you [who truly repent] with the Holy Spirit and [you who remain unrepentant] with fire.

Do not carry a money belt, a provision bag, or [extra] sandals; and do not greet anyone along the way [who would delay you].

But the father said to his servants, ‘Quickly bring out the best robe [for the guest of honor] and put it on him; and give him a ring for his hand, and sandals for his feet.

And He said to them, “When I sent you out without a money belt and [provision] bag and [extra] sandals, did you lack anything?” They answered, “Nothing.”
