Genesis 8:8-11

8Then he sent out a dove from him, to see if the water was abated from the face of the land;

9but the dove found no resting place for the sole of her foot, so she returned to him into the ark, for the water was on the 1surface of all the earth. Then he put out his hand and took her, and brought her into the ark to himself.

10So he waited yet another seven days; and again he sent out the dove from the ark.

11The dove came to him toward 2evening, and behold, in her 3beak was a freshly picked olive leaf. So Noah knew that the water was abated from the earth.
