Lamentations 2:18

Their heart. — The possessive pronoun does not refer to any immediate antecedent, but points, with a wild abruptness, to the mourners of Zion. Yet more boldly their cry is an appeal to the “wall” of Zion (comp. Lamentations 2:8, and Isaiah 14:31), to take up its lamentation, as though it were a human mourner.

Like a river. — Better, like a torrent.

The apple of thine eye. — Literally, “the daughter,” as in the English phrase, the “pupil” of the eye.
