Genesis 8:8-10

8Then Noah sent out a dove to see if the water level had fallen below the surface of the land.

9But 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.

10He waited another seven days and again sent the dove out from the ark.
