'Light' in the Bible

I looked at the earth, and it was formless and void, at the heavens, and there was no light there.

Give glory to the LORD your God before he brings darkness, before your feet stumble on the mountains at twilight. You hope for light, but he turns it into deep darkness. He changes it into heavy gloom.

I'll destroy the sounds of gladness and rejoicing from them, the sounds of the bridegroom and the bride, the sound of the hand mill and also the light of the lamp.

This is what the LORD says, who gives the sun for light by day, the laws that govern the moon and stars for light by night, and who stirs up the sea so that its waves roar. The LORD of the Heavenly Armies is his name:

Perhaps their pleas for help will come to the LORD's attention, and each of them will turn from his evil lifestyle in light of the great anger and wrath that the LORD has declared against this people."
