'Blood' in the Bible

And I will shew wonders in the heavens and in the earth, blood, and fire, and pillars of smoke.

The sun shall be turned into darkness, and the moon into blood, before the great and the terrible day of the LORD come.

Egypt shall be a desolation, and Edom shall be a desolate wilderness, for the violence against the children of Judah, because they have shed innocent blood in their land.

For I will cleanse their blood that I have not cleansed: for the LORD dwelleth in Zion.
