Genesis 8:8-12

8 Then he sent out a dove from him, to see if the water was abated from the face of the land;
9 but the dove found no resting place for the sole of her foot, so she returned to him into the ark, for the water was on the surface of all the earth. Then he put out his hand and took her, and brought her into the ark to himself.
10 So he waited yet another seven days; and again he sent out the dove from the ark.
11 The dove came to him toward evening, and behold, in her beak was a freshly picked olive leaf. So Noah knew that the water was abated from the earth.
12 Then he waited yet another seven days, and sent out 1the dove; but she did not return to him again.
