Genesis 8:7-9

Young's Literal Translation

⁷ and he sendeth forth the raven, and it goeth out, going out and turning back till the drying of the waters from off the earth.

⁸ And he sendeth forth the dove from him to see whether the waters have been lightened from off the face of the ground,

⁹ and the dove hath not found rest for the sole of her foot, and she turneth back unto him, unto the ark, for waters [are] on the face of all the earth, and he putteth out his hand, and taketh her, and bringeth her in unto him, unto the ark.
