Genesis 8:5-7

Revised Standard Version Catholic Edition

⁵ And the waters continued to abate until the tenth month; in the tenth month, on the first day of the month, the tops of the mountains were seen.

⁶ At the end of forty days Noah opened the window of the ark which he had made, ⁷ and sent forth a raven; and it went to and fro until the waters were dried up from the earth.
