Charles Spurgeon Commentary Genesis 8:3-5

"and the waters returned from off the earth continually: and after the end of a hundred and fifty days the waters decreased. And the ark rested in the seventh month, on the seventeenth day of the month, upon the mountains of Ararat. And the waters decreased continually until the tenth month: in the tenth month, on the first day of the month, were the tops of the mountains seen." — Genesis 8:3-5 (ASV)

God told Noah when to go into the ark, but He did not tell him when he would come out again. The Lord told Noah when to go in, because it was necessary for him to know that; but He did not tell him when he would come out, because it was unnecessary for him to know that. God always lets His people know what is practically for their good. There are many curious points on which we would like to have information, but God has not revealed it, and when He has not revealed anything, we had better not try to unravel the mystery.

No good comes from prying into unrevealed truth. Noah knew that he would come out of the ark one day, for was he not preserved there to be a seed—to keep the race alive? Noah was not told when he would be released, and the Lord does not tell you when your trouble will come to an end. It will come to an end; therefore, wait, be patient, and do not desire to know the time of your deliverance. We would know too much if we knew all that will happen in the future.

It is quite enough for us if we do our duty in the present and trust God for the rest. Still, I think that Noah must have been very pleased when he felt the ark grating at last on the mountains of Ararat. He could not build a dock for his big ship, but God had prepared a berth for it on the mountainside. Now, as he looked out, he could see, here and there, a mountaintop rising like an island out of the great expanse of water.
