Genesis 8:9-11

New Revised Standard Version Catholic Edition

⁹ but the dove found no place to set its foot, and it returned to him to the ark, for the waters were still on the face of the whole earth. So he put out his hand and took it and brought it into the ark with him. ¹⁰ He waited another seven days, and again he sent out the dove from the ark; ¹¹ and the dove came back to him in the evening, and there in its beak was a freshly plucked olive leaf; so Noah knew that the waters had subsided from the earth.
