'Turn' in the Bible

Because in spite of suffering you have guarded My word, I in turn will guard you from that hour of trial which is soon coming upon the whole world, to put to the test the inhabitants of the earth.

They have power given to them to seal up the sky, so that no rain may fall so long as they continue to prophesy; and power over the waters to turn them into blood, and to smite the earth with various plagues whenever they choose to do so.
