18 and the waters are mighty, and multiply exceedingly upon the earth; and the ark goeth on the face of the waters. 19 And the waters have been very very mighty on the earth, and covered are all the high mountains which 'are' under the whole heavens; 20 fifteen cubits upwards have the waters become mighty, and the mountains are covered;

21 and expire doth all flesh that is moving on the earth, among fowl, and among cattle, and among beasts, and among all the teeming things which are teeming on the earth, and all mankind; 22 all in whose nostrils 'is' breath of a living spirit—of all that 'is' in the dry land—have died. 23 And wiped away is all the substance that is on the face of the ground, from man unto beast, unto creeping thing, and unto fowl of the heavens; yea, they are wiped away from the earth, and only Noah is left, and those who 'are' with him in the ark; 24 and the waters are mighty on the earth a hundred and fifty 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.
