He hath led me, and brought me into darkness, but not into light. I am the man that hath seen affliction - Jeremiah's own affliction in the dungeon of Malchiah (Jeremiah 38:6): that of his countrymen also in the siege. Both were types of that of Christ.
Verse 2. He hath led me ... into darkness - calamity. Light - prosperity.
Verse 3. He turneth his hand - to inflict again and again new strokes upon me. "His hand," which once used to protect me, now continually strikes me. "Against me is He turned ... He turneth against me" implies repeated inflictions.
