English: where does “the apple of your eye” come from?
Self-tutoring about expressions: the tutor mentions one.
When I was a kid, I came to understand that “the apple of your eye” means someone you are fond of – perhaps most fond of. Yet, where does that saying come from?
It’s found in the Bible, Pslam 17:8. David asks God to “Keep me as the apple of Your eye.”
