'Dark' in the Bible

And he will roar over him on that day like [the] roaring of [the] sea, and [if] one looks to the land, look! Darkness! Distress! And [the] light grows dark with its clouds.

Ah! Those who make a plan deep, to hide [it] from Yahweh, and their deeds are in a dark place. And they say, "Who sees us? And who knows us?"
