Genesis 7:17-19

Amplified Bible

¹⁷ The flood [the great downpour of rain] was forty days and nights on the earth; and the waters increased and lifted up the ark, and it floated [high] above the land. ¹⁸ The waters became mighty and increased greatly on the earth, and the ark floated on the surface of the waters. ¹⁹ The waters prevailed so greatly and were so mighty and overwhelming on the earth, so that all the high mountains everywhere under the heavens were covered.
