'Blood' in the Bible

And I will let wonders be seen in the heavens and on the earth, blood and fire and pillars of smoke.

The sun will be made dark and the moon turned to blood, before the great day of the Lord comes, a day to be feared.

Egypt will be a waste and Edom a land of destruction, because of the evil done to the children of Judah, because they have let blood be drained out in their land without cause.

And I will send punishment for their blood, for which punishment has not been sent, for the Lord is living in Zion.
