Lamentations 2:18

They cried unto God seriously, though not sincerely; from their heart, though not with their whole heart; either by the wall, or upon the wall, or (which is judged most probable) by occasion of the breaches made in the wall. Upon this he turns his discourse to the wall itself, and calls to it, or to those that were upon it, or near it, incessantly to mourn. Let not the apple of thine eye cease; in the Hebrew it is, let not the daughter of thine eye cease. We call it the apple; the Latins, the pupil, or babe, of the eye.
