Genesis 8:11

And the dove returned to him in the evening, and had a leaf of olive, a sprig in her mouth; and Noe knew that the water had ceased from off the earth.

And 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.

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