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.
