Thomas Aquinas Commentary Lamentations 1:7

"Jerusalem remembereth in the days of her affliction and of her miseries all her pleasant things that were from the days of old: When her people fell into the hand of the adversary, and none did help her, The adversaries saw her, they did mock at her desolations." — Lamentations 1:7 (ASV)

Here, he weeps over the misfortune he recalls from the past.

1. First, he addresses the memory of past things: past affliction, which brings disgust when remembered; prevarication (that is, sins), which stirs the conscience to remorse; and all her desirable things, meaning the prosperities that cause and ignite sinful desires. I will recount to you all my years in the bitterness of my soul (Isaiah 38:15).
2. Second, he presents the suffering of present evils: when her people fell into the enemy’s hand. Tribulation is very near: for there is none to help me (Psalms 21:12).
3. Third, he describes the contempt of her enemies: the enemies have seen her, and have mocked at her sabbaths, and all those things that pertained to religious worship. Her festival days were turned into mourning, her sabbaths into reproach, her honors were brought to nothing .

The explanations of the rhetorical topics concerning the literal and mystical senses are sufficiently addressed in the Glosses.
