'Let There Be' in the Bible

But he himself, turning back from the stone images at Gilgal, said, I have something to say to you in secret, O king. And he said, Let there be quiet. Then all those who were waiting before him went out.

And Gideon said unto God, Let not thine anger be hot against me, and I will speak but this once: let me prove, I pray thee, but this once with the fleece; let it now be dry only upon the fleece, and upon all the ground let there be dew.
