Matthew Henry · Verses 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, Psa 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.
