Genesis 8:6-12

Forty days later Noah opened the window he had made in the boat, and he sent out a raven. It flew here and there until the water had dried up from the earth. Then Noah sent out a dove to find out if the water had dried up from the ground. The dove could not find a place to land because water still covered the earth, so it came back to the boat. Noah reached out his hand and took the bird and brought it back into the boat. After seven days Noah again sent out the dove from the boat, and that evening it came back to him with a fresh olive leaf in its mouth. Then Noah knew that the ground was almost dry. Seven days later he sent the dove out again, but this time it did not come back.
