Genesis 8:9-11

American Standard Version

⁹ but 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. ¹⁰ And he stayed yet other seven days; and again he sent forth the dove out of the ark; ¹¹ and the dove came in to him at eventide; and, lo, in her mouth ^[a]an olive-leaf plucked off: so Noah knew that the waters were abated from off the earth.
