19 Of every living thing of all flesh, you shall bring two of every sort into the ship, to keep them alive with you. They shall be male and female.

And of every living thing of all flesh. "All flesh" is the name he gives to animals of whatsoever kind they may be. He says they went in two and two; not that a single pair of each kind was received into the ark, (for we shall soon see that there were three pairs of the clean kinds, and one animal over, which Noah afterwards offered in sacrifice;) but whereas here mention is made only of offspring, he does not expressly state the number, but simply couples males with females, that Noah might hence perceive how the world was to be replenished.
To keep them alive - God might have destroyed all the animal creation, and created others to occupy the new world, but he chose rather to preserve those already created. The Creator and Preserver of the universe does nothing but what is essentially necessary to be done. Nothing should be wantonly wasted; nor should power or skill be lavished where no necessity exists; and yet it required more means and economy to preserve the old than to have created new ones. Such respect has God to the work of his hands, that nothing but what is essential to the credit of his justice and holiness shall ever induce him to destroy any thing he has made.
And of every living thing of all flesh, two of every sort shalt thou bring into the ark,.... That is, of fowls, cattle, and creeping things, as after explained; and two of each sort at least were to be brought, as Jarchi observes, and not fewer; though of the clean sort there were to be more, even seven, as after directed; and these were to be brought, that they might preserve their species, as it follows:
to keep them alive with thee; to be fed and nourished by him in the ark, while others perished by the flood, that so they might propagate their own species, and be continued, for which reason it is further ordered:
they shall be male and female; not any two, but one male and one female, for the end before mentioned.
