'It is I' in the Bible

an old leprosy it is in the skin of his flesh, and the priest hath pronounced him unclean; he doth not shut him up, for he is unclean.

And if the bright spot stay in its place, it hath not spread in the skin, and is become weak; a rising of the burning it is, and the priest hath pronounced him clean; for it is inflammation of the burning.

And a man who taketh his brother's wife -- it is impurity; the nakedness of his brother he hath uncovered; childless they are.
