'Dark' in the Bible

And he said to me, "Have you seen, son of man, what the elders of the house of Israel [are] doing in the dark, each in the inner rooms of his idol, for [they are] saying, 'Yahweh [is] not seeing us; Yahweh has abandoned the land.'"

And at Tahpanhes the day will become dark when I break the yoke of Egypt, and in it the majesty of its strength will come to an end. A cloud will cover it, and its daughters will go into captivity.

And I will cover [you] at extinguishing your heavens, and I will make dark their stars, and I will cover [the] sun with the cloud, and [the] moon will not give its light.

All sources of light in the heavens, I will make them dark over you, and I will put darkness on your land,'" {declares} the Lord Yahweh.
