Genesis 8:6-9

6And it came to pass at the end of forty days, that Noah opened the window of the ark which he had made:

7and he sent forth a raven, and it went forth to and fro, until the waters were dried up from off the earth.

8And he sent forth a dove from him, to see if the waters were abated from off the face of the ground;

9but the dove found no rest for the sole of her foot, and she returned unto him to the ark, for the waters were on the face of the whole earth: and he put forth his hand, and took her, and brought her in unto him into the ark.
