Genesis 8:11-13

New King James Version

¹¹ Then the dove came to him in the evening, and behold, a freshly plucked olive leaf was in her mouth; and Noah knew that the waters had receded from the earth. ¹² So he waited yet another seven days and sent out the dove, which did not return again to him anymore.

¹³ And it came to pass in the six hundred and first year, in the first month, the first day of the month, that the waters were dried up from the earth; and Noah removed the covering of the ark and looked, and indeed the surface of the ground was dry.
