'It is I' in the Bible

"Three men are now looking for you. Rise, go down and go with them, nothing doubting; for it is I who have sent them."

To them he said: "You know, yourselves, that it is illegal for a Jew to associate with or to visit one of another nation; but God has taught me that I should not call any man common or unclean. For this reason, when sent for, I came without demur.
