Genesis 7:17-20

MSB(i) 17 For forty days the flood kept coming on the earth, and the waters rose and lifted the ark high above the earth. 18 So the waters continued to surge and rise greatly on the earth, and the ark floated on the surface of the waters. 19 Finally, the waters completely inundated the earth, so that all the high mountains under all the heavens were covered. 20 The waters rose and covered the mountaintops to a depth of fifteen cubits.
