<P> Their heart cried unto the Lord, O wall of the daughter of Zion, let tears run down like a river day and night: give thyself no rest; let not the apple of thine eye cease . </P> <P> as well as in Zechariah 2: 8 </P> <P> For thus saith the LORD of hosts; After the glory hath he sent me unto the nations which spoiled you: for he that toucheth you toucheth the apple of his eye . </P> <P> The original Hebrew for this idiom, in all but Zechariah 2: 8, was' iyshown' ayin (אישון עין). The expression refers to the pupil, and probably simply means "dark part of the eye" (other biblical passages use' iyshown with the meaning dark orobscure, and having nothing whatsoever to do with the eye). There is, however, a popular notion that' iyshown is a diminutive of "man" (' iysh), so that the expression would literally mean "Little Man of the Eye ." </P>

Where does apple of my eye come from
