Passage
He hath led me and caused me to walk in darkness, and not in light.
He hath led me and caused me to walk in darkness, and not in light.
Lamentations 3:1 I am the man that hath seen affliction by the rod of his wrath.
Lamentations 3:2 He hath led me and caused me to walk in darkness, and not in light.
Lamentations 3:3 Surely against me he turneth his hand again and again all the day.
Lamentations 3:4 My flesh and my skin hath he made old; he hath broken my bones.
The verse centers on "light", "darkness", "hath", "caused", and "walk". It is saying that the contrast between light and darkness marks a real divide in how people respond to God's work.
The nearby context moves from verse 1's "I am the man that hath seen..." into verse 3's "Surely against me he turneth his hand...", so "light" and "darkness" belong inside that flow. In Lamentations context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "light" and "darkness" with trust shaped by these words, not by a vague optimism outside the passage.
