Jamieson, Fausset and Brown on Lamentations 1:15

15. trodden, &c.--Maurer, from Syriac root, translates, "cast away"; so 2Ki 23:27. But Psa 119:118, supports English Version.

in ... midst of me--They fell not on the battlefield, but in the heart of the city; a sign of the divine wrath.

assembly--the collected forces of Babylon; a very different "assembly" from the solemn ones which once met at Jerusalem on the great feasts. The Hebrew means, literally, such a solemn "assembly" or feast (compare La 2:22).

trodden ... virgin ... in a wine-press--hath forced her blood to burst forth, as the red wine from the grapes trodden in the press (Is 63:3; Re 14:19, 20; 19:15).
