GENESIS 8:6-12 (KJV)
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, which went forth to and fro, until the waters were dried up from off the earth.
8Also 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 into the ark, for the waters were on the face of the whole earth: then he put forth his hand, and took her, and pulled her in unto him into the ark.
10And he stayed yet other seven days; and again he sent forth the dove out of the ark;
11And the dove came in to him in the evening; and, lo, in her mouth was an olive leaf pluckt off: so Noah knew that the waters were abated from off the earth.
12And he stayed yet other seven days; and sent forth the dove; which returned not again unto him any more.
