Genesis 8:5-7

King James Version

⁵ And the waters decreased continually until the tenth month: in the tenth month, on the first day of the month, were the tops of the mountains seen.

⁶ And it came to pass at the end of forty days, that Noah opened the window of the ark which he had made:

⁷ And he sent forth a raven, which went forth to and fro, until the waters were dried up from off the earth.
