Here we have the effects and evidences of the ebbing of the waters. 1. The ark rested. This was some satisfaction to Noah, to feel the house he was in upon firm ground, and no longer movable. It rested upon a mountain, whither it was directed, not by Noah's prudence (he did not steer it), but by the wise and gracious providence of God, that it might rest the sooner.
Note, God has times and places of rest for his people after their tossings; and many a time he provides for their seasonable and comfortable settlement without their own contrivance and quite beyond their own foresight.
The ark of the church, though sometimes tossed with tempests, and not comforted (Isaiah 54:11), yet has its rests, Acts 9:31. 2. The tops of the mountains were seen, like little islands, appearing above the water.
We must suppose that they were seen by Noah and his sons; for there were none besides to see them. It is probable that they had looked through the window of the ark every day, like the longing mariners, after a tedious voyage, to see if they could discover land, or as the prophet's servant (1 Kings 18:43-44), and at length they spy ground, and enter the day of the discovery in their journal.
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.
