Genesis 8:3-5

The waters returned from off the earth continually Hebrews they were going and returning; a gradual departure. The heat of the sun exhaled much, and perhaps the subterraneous caverns soaked in more. And the ark rested upon the mountains of Ararat Or, Armenia, whither it was directed, not by Noah's prudence, but the wise providence of God. The tops of the mountains were seen Like little islands appearing above water. They felt ground above forty days before they saw it, according to Dr. Lightfoot's computation, whence he infers, that if the waters decreased proportionably, the ark drew eleven cubits in water.
