Passage
Shall not the day of Jehovah be darkness, and not light? even very dark, and no brightness in it?
Shall not the day of Jehovah be darkness, and not light? even very dark, and no brightness in it?
Amos 5:18 Woe unto you that desire the day of Jehovah! To what end is the day of Jehovah for you? It shall be darkness and not light:
Amos 5:19 as if a man fled from a lion, and a bear met him; or went into the house and leaned his hand on the wall, and a serpent bit him.
Amos 5:20 Shall not the day of Jehovah be darkness, and not light? even very dark, and no brightness in it?
Amos 5:21 I hate, I despise your feasts, and I will not smell [a sweet odour] in your solemn assemblies.
Amos 5:22 For if ye offer up unto me burnt-offerings and your oblations, I will not accept [them]; neither will I regard the peace-offerings of your fatted beasts.
The verse centers on "light", "darkness", "shall", "jehovah", "even", "very", and "brightness". 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 19's "as if a man fled from a..." into verse 21's "I hate I despise your feasts and...", so "light" and "darkness" belong inside that flow. In Amos 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.
