Matthew Poole and continuators on Lamentations 3:65

65 Give them sorrow of heart , thy curse unto them.

The word translated sorrow of heart is found no where else in Holy Writ, which makes a certain particular explication of it to be difficult, and hath given Interpreters a strange liberty in translating it, shield, sorrow, and grief, obstinacy or hardness of heart, perplexi[illegible: 1 letter]y, abjection or breaking of heart; the best guides we have to direct us in the sense of it are. 1 The other things joyned with it, persecution, destruction, a recompense according to their works, so that some afflictive evil of an heavy nature is certainly signified by it. 2. The Analogy of Faith which restraineth us from wishing or praying for spiritual or eternal evils against our worst Enemies, it therefore probably signifies, such perplexity of mind, and breakings of mind as commonly attend a state of great affliction.

Marginal references: Or, obstinacy of hea[illegible: 1 letter]t.
