'Black' in the Bible

For this shall the earth mourn, and the heavens above be black: because I have spoken it, I have purposed it, and will not repent, neither will I turn back from it.

For the hurt of the daughter of my people am I hurt; I am black; astonishment hath taken hold on me.

Judah mourneth, and the gates thereof languish; they are black unto the ground; and the cry of Jerusalem is gone up.
