Genesis 8:9 WEB

⁷  and he sent forth a raven. It went back and forth, until the waters were dried up from off the earth.

⁸  He sent forth a dove from him, to see if the waters were abated from off the surface of the ground,

⁹  but the dove found no place to rest her foot, and she returned to him into the ark; for the waters were on the surface of the whole earth. He put forth his hand, and took her, and brought her to him into the ark.

¹⁰  He stayed yet another seven days; and again he sent forth the dove out of the ark.

¹¹  The dove came back to him at evening, and, behold, in her mouth was an olive leaf plucked off. So Noah knew that the waters were abated from off the earth.
