Genesis 8:6-10

At the end of [another] forty days Noah opened the window of the ark which he had made; and he sent out a raven, which flew here and there until the waters were dried up from the earth. Then Noah sent out a dove to see if the water level had fallen below the surface of the land. But the dove found no place on which to rest the sole of her foot, and she returned to him to the ark, for the waters were [still] on the face of the entire earth. So he reached out his hand and took the dove, and brought her into the ark. He waited another seven days and again sent the dove out from the ark.
