'Thong' in the Bible

that I will not take a thread or a sandal thong or anything that is yours, for fear you would say, ‘I have made Abram rich.’

And he was preaching, and saying, “After me One is coming who is mightier than I, and I am not fit to stoop down and untie the thong of His sandals.

John answered and said to them all, “As for me, I baptize you with water; but One is coming who is mightier than I, and I am not fit to untie the thong of His sandals; He will baptize you with the Holy Spirit and fire.

It is He who comes after me, the thong of whose sandal I am not worthy to untie.”
