Commentaire sur La Genèse 9:10

חית הארץ אתכם AND EVERY ANIMAL OF THE EARTH WITH YOU or, THAT ARE WITH YOU — those which go about with human beings.

ואת כל הנפש אשר אתכם, the ones which had been in the ark with you; this is spelled out shortly by the words מכל יוצאי התבה, “I will make a covenant with all the species of creatures that came out of the ark. None of these species will again become subject to extinction.” G’d said further: לכל חית הארץ, in order to make the meaning of what had been written before perfectly clear. In Bereshit Rabbah it is pointed out that these words include all the subsequent generations of these animals, just as the subsequent generations of Noach’s sons and their wives were included in the blessing as we know from the words ואת זרעכם אחריכם, “and your offspring after you.”

Unclean birds, and crawlers. שקצים means unclean fowl, of which it says (Vayikra 11:13), שקץ הם. And רמשים has its usual meaning. (Maharshal)
