Genesis 8:10-12

Young's Literal Translation

¹⁰ And he stayeth yet other seven days, and addeth to send forth the dove from the ark;

¹¹ and the dove cometh in unto him at even-time, and lo, an olive leaf torn off in her mouth; and Noah knoweth that the waters have been lightened from off the earth.

¹² And he stayeth yet other seven days, and sendeth forth the dove, and it added not to turn back unto him any more.
