Matthew Henry Presbyterian @wholebiblehenry

We are here told, I. How long the flood was increasing - forty days, Gen 7:17. The profane world, who believed not that it would come, probably when it came flattered themselves with hopes that it would soon abate and never come to extremity; but still it increased, it prevailed. Note, 1. When God judges he will overcome.

Commenting on Genesis 7:17-20

John Gill Reformed Baptist @doctorgill

And all flesh died that moved upon the earth,.... That had animal life in them, of which motion was a sign: both of fowl, and of cattle, and of beast, and of every creeping thing that creepeth on the earth; excepting those that were in the ark.
