Bible Notes Online - Lamentations 5 - ESV
Commentary

v1: Trusting in God, contrast Jer 44.15-19; many of the people had deliberately chosen idolatry.

v2-3: The land, so precious to the people, for God had given it, was handed over to foreigners.

v4-10: The bare necessities of life wee hard to find, they had a constant struggle for survival.

v11-15: The people all suffered. No one could find a group of people exempt from the pain.

v16: The key to the book, "Woe to us, for we have sinned!" The long, sorry, saga, of decline and defeat is summed up so aptly.

v17-18: The people still believed that their future was tied up with the condition of Mount Zion, and therefore they sorrowed over it. No longer the place of joy and dancing (v15), but desolate, the home of wild animals.

v19-20: The eternity of God; without Him there is no hope. God is in control, in every generation. But why, comes the question, was this generation forgotten?

v21-22: Ultimately, God would show His faithfulness again. Jeremiah knew that the suffering would end, for God had promises still to be fulfilled; and His throne is forever.
