'I Am Not Worthy' in the Bible

I immerse you in water, in order to repentance; but he that comes after me is mightier than I, whose sandals I am not worthy to carry. He will immerse you in the Holy Spirit and in fire:

And the centurion answering, said: Lord, I am not worthy that thou shouldst come under my roof; but say in a word only, and my servant shall be restored to health.

and he preached, saying: There comes after me One mightier than I, the strap of whose sandals I am not worthy to stoop down and loose.

John answered them all, saying: I indeed immerse you in water; but there comes One mightier than I, the strap of whose sandals I am not worthy to loose; he will immerse you in the Holy Spirit and in fire.

And Jesus went with them. And when he was now not far from the house, the centurion sent friends to him, and said to him: Lord, give thyself no trouble; for I am not worthy that thou shouldst come under my roof.

He it is, who, though he comes after me, is now before me; the strap of whose sandal I am not worthy to loose.

And as John was finishing his course, he said: Who do you suppose that I am? I am not he; but behold, there is coming after me one, the sandals of whose feet I am not worthy to loose.

For I am the least of the apostles, and I am not worthy to be called an apostle, because I persecuted the church of God.
