Rashi on Genesis 8:17/רש"י על בראשית ח׳:י״ז

1הוצא BRING FORTH — The Ketib is הוצא and the Keri היצא — ;היצא means, “tell them to go forth”, הוצא means, ‘‘if they do not wish (if they refuse) to go forth, you make them go out”.

2ושרצו בארץ THAT THEY MAY BRING FORTH ABUNDANTLY IN THE EARTH but not in the Ark: this teaches that cattle and fowls also were separated, male and female, in the Ark (Genesis Rabbah 34:8).
