I called upon thy name, O LORD, out of the low dungeon.
We certainly see that the Prophet had an inward conflict, which also all the faithful experience, for the spirit fights against the flesh, as Paul teaches us. (Galatians 5:17.) Though, then, he on the one hand apprehended death, he yet ceased not to flee to God; for faith strengthened his mind so that he did not succumb, but on the contrary he firmly rejected the temptation presented to him.
Faith and fear wrestled in the Prophet's breast throughout this lament, but faith gets the last word. He found God heard his prayers even from the lowest dungeon; his weeping never hindered his praying. From such depths a man may find a way of access to God in the highest heavens.

Commenting on Lamentations 3:55-66
Thou hast seen all their vengeance,.... The spirit of revenge in them; their wrath and fury, and how they burn with a desire of doing mischief; as well as their revengeful actions, carriage, and behaviour: and all their imaginations against me; their secret contrivances of mischief, their plots and schemes they devise to do hurt unto me.
