'It is I' in the Bible

And if, when the priest seeth it, behold, it is in sight lower than the skin, and the hair of it is turned white; the priest shall pronounce him unclean: it is a plague of leprosy broken out of the boil.

Then the priest shall look upon it: and behold, if the hair in the bright spot is turned white, and it is in sight deeper than the skin: it is a leprosy broken out of the burning: wherefore the priest shall pronounce him unclean: it is the plague of leprosy.

Then the priest shall see the plague: and behold, if it is in sight deeper than the skin, and there is in it a yellow thin hair; then the priest shall pronounce him unclean: it is a dry scall, even a leprosy upon the head or beard.
