And of all the living. - For the sake of Noah, the animal species also shall be preserved, "two of each, male and female." They are to come in pairs for propagation. The fowl, the cattle, the creeping thing or smaller animals, are to come. From this it appears that the wild animals are not included among the inmates of the ark. (See Genesis 7:2-3, Genesis 7:8.) The word "all" is not to be pressed beyond the specification of the writer. As the deluge was universal only in respect to the human race, it was not necessary to include any animals but those that were near man, and within the range of the overwhelming waters. Fodder and other provisions for a year have to be laid in.

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.

And of every living thing of all flesh, two of every sort shalt thou bring into the ark, to keep them alive with thee; they shall be male and female.

[1] two of every sort

Cf Gen 7:2.

In addition to two animals, etc., commanded (Gen 6.19) to be preserved for future increase ("they shall be male and female"), the further command was given more than 100 years later to take of clean beasts, i.e, acceptable for sacrifice, seven each. Exodus gives ten such beasts, or but seventy in all. Modern ships carry hundreds of live beasts, with their food, besides scores of human beings.

6:12-21 God told Noah his purpose to destroy the wicked world by water. The secret of the Lord is with them that fear him, Ps 25:14. It is with all believers, enabling them to understand and apply the declarations and warnings of the written word. God chose to do it by a flood of waters, which should drown the world. As he chooses the rod with which he corrects his children, so he chooses the sword with which he cuts off his enemies. God established his covenant with Noah. This is the first place in the Bible where the word 'covenant' is found; it seems to mean, 1. The covenant of providence; that the course of nature shall be continued to the end of time. 2. The covenant of grace; that God would be a God to Noah, and that out of his seed God would take to himself a people. God directed Noah to make an ark. This ark was like the hulk of a ship, fitted to float upon the waters. It was very large, half the size of St. Paul's cathedral, and would hold more than eighteen of the largest ships now used. God could have secured Noah without putting him to any care, or pains, or trouble; but employed him in making that which was to be the means to preserve him, for the trial of his faith and obedience. Both the providence of God, and the grace of God, own and crown the obedient and diligent. God gave Noah particular orders how to make the ark, which could not therefore but be well fitted for the purpose. God promised Noah that he and his family should be kept alive in the ark. What we do in obedience to God, we and our families are likely to have the benefit of. The piety of parents gets their children good in this life, and furthers them in the way to eternal life, if they improve it.
