Genesis 8:8-11

8He also released a dove to see if the water had receded and it could find dry ground.

9But the dove could find no place to land because the water still covered the ground. So it returned to the boat, and Noah held out his hand and drew the dove back inside.

10After waiting another seven days, Noah released the dove again.

11This time the dove returned to him in the evening with a fresh olive leaf in its beak. Then Noah knew that the floodwaters were almost gone.
