And there was also an inscription written over him in Greek, and Roman, and Hebrew letters: This is the King of the Jews.

The Jews therefore wondered, saying, How knows this man letters, having never learned?

and asked of him letters to Damascus, to the synagogues, so that if he found any who were of the way, both men and women, he might bring them bound to Jerusalem.

And they said to him, For our part, we have neither received letters from Judaea concerning thee, nor has any one of the brethren who has arrived reported or said anything evil concerning thee.

And when I am arrived, whomsoever ye shall approve, these I will send with letters to carry your bounty to Jerusalem:

that I may not seem as if I was frightening you by letters:

because his letters, he says, are weighty and strong, but his presence in the body weak, and his speech naught.

Let such a one think this, that such as we are in word by letters when absent, such also present in deed.

and that from a child thou hast known the sacred letters, which are able to make thee wise unto salvation, through faith which is in Christ Jesus.
