18 As the waters rose higher and higher above the ground, the boat floated safely on the surface. 19 Finally, the water covered even the highest mountains on the earth, 20 rising more than twenty-two feet above the highest peaks.

21 All the living things on earth died-birds, domestic animals, wild animals, small animals that scurry along the ground, and all the people. 22 Everything that breathed and lived on dry land died. 23 God wiped out every living thing on the earth-people, livestock, small animals that scurry along the ground, and the birds of the sky. All were destroyed. The only people who survived were Noah and those with him in the boat. 24 And the floodwaters covered the earth for 150 days.

Matthew Henry's Commentary on Genesis 7:18-24

Commentary on Genesis 7:17-20

(Read Genesis 7:17-20)

The flood was increasing forty days. The waters rose so high, that the tops of the highest mountains were overflowed more than twenty feet. There is no place on earth so high as to set men out of the reach of God's judgments. God's hand will find out all his enemies, Psalm 21:8. When the flood thus increased, Noah's ark was lifted up, and the waters which broke down every thing else, bore up the ark. That which to unbelievers betokens death unto death, to the faithful betokens life unto life.

Commentary on Genesis 7:21-24

(Read Genesis 7:21-24)

All the men, women, and children, that were in the world, excepting those in the ark, died. We may easily imagine what terror seized them. Our Saviour tells us, that till the very day that the flood came, they were eating and drinking, 2 Peter 2:5. How tremendous will be the day of judgment and perdition of ungodly men! Happy they who are part of Christ's family, and safe with him as such; they may look forward without dismay, and rejoice that they shall triumph, when fire shall burn up the earth, and all that therein is. We are apt to suppose some favourable distinctions in our own case or character; but if we neglect, refuse, or abuse the salvation of Christ, we shall, notwithstanding such fancied advantages, be destroyed in the common ruin of an unbelieving world.
