Genesis 8:7-12

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. The dove came back to him in the evening, and there, in her beak, was a fresh olive leaf. So Noah knew that the water level had subsided from the earth. Then he waited another seven days and sent out the dove, but she did not return to him again.
