Comentario sobre Génesis 7:2

הטהורה CLEAN—It means those cattle which will in future be permitted to Israel as clean; we thus learn that Noah studied the Torah.

הטהורה, at that time all of the pure animals [including free roaming ones] were acceptable as potential offerings to G’d.

מכל הבהמה הטהורה תקח לך שבעה. "Take with you for yourself seven (pairs) each of the pure mammals." The expression תקח לך has a dual meaning. 1) He should make the effort to secure these animals as his eventual "payment" [expression of his gratitude to G'd for being saved. Ed.]. The words "for your own self" are therefore justified. If not for this verse we might have asked who had given Noach permission to simply kill these animals? After all, Noach had been commanded to keep the species alive, not to slaughter them! Noach would have reasoned that inasmuch as these categories of beasts are urgently needed for man G'd had commanded to take 7 pairs instead of just a single pair. G'd therefore had to indicate to Noach that the greater number was for his own good, not for the general good. Had Noach simply wanted to slaughter these animals and to eat their meat this too would have been in order.
