18 The waters rose and increased greatly on the earth, and the ark floated on the surface of the water.

Matthew Henry's Commentary on Genesis 7:18

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.
