Genesis 9:9 - Ellicott's Commentary On The Whole Bible

I, behold, I establish my covenant... The covenant between God and man is thus solemnly introduced as Elohim’s personal act. No covenant is mentioned as existing between Elohim and the antediluvian world; but distinctly now there is a step onward in all respects, and man, in the renovated earth after the flood, is brought nearer to God by being admitted into covenant with Him. And not only is man included in the covenant, but, first, those animals which had been with Noah in the ark; and, secondly, those which had not been admitted there. For the words of Genesis 9:10 are: “From all that go out of the ark unto every beast of the earth” (the larger world). To such straits are those reduced who hold to the theory of a universal deluge, that Kalisch argues that it means the fish, as if fishes would be destroyed by a second flood any more than they were by the first. Plainly, the words imply the existence of a larger world-sphere than that in connection with Noah, and give the assurance that not only those now providentially preserved, but the animals everywhere, shall never again be in danger of a similar extinction.
