'Light' in the Bible

And he said unto me, Seest thou, son of man? Is it a light thing to the house of Judah to commit the abominations which they commit here, that they yet fill the land with violence, and keep provoking me afresh to anger? And behold, they put the branch to their nose.

In thee have they made light of father and mother; in the midst of thee have they dealt by oppression with the stranger; in thee have they vexed the fatherless and the widow.

And when I shall put thee out, I will cover the heavens, and make the stars thereof black; I will cover the sun with a cloud, and the moon shall not give her light.
