Genesis 8:6-12

⁶Then it came about at the end of forty days, that Noah opened the window of the ark which he had made; ⁷and he sent out a raven, and it flew here and there until the water was dried up from the earth. ⁸Then he sent out a dove, to see if the water was low on the surface of the land; ⁹but the dove found no resting place for the sole of its foot, so it returned to him in the ark, for the water was on the surface of all the earth. Then he put out his hand and took it, and brought it into the ark to himself. ¹⁰So he waited another seven days longer; and again he sent out the dove from the ark. ¹¹And the dove came to him in the evening, and behold, in its beak was a fresh olive leaf. So Noah knew that the water was low on the earth. ¹²Then he waited another seven days longer, and sent out the dove; but it did not return to him again.
