Genesis 8:13

Noah waited some time, and then, on the first day of the first month, in the 601st year of his life, removed the covering from the ark, that he might obtain a freer prospect over the earth. He could see that the surface of the earth was dry; but it was not till the 27th day of the second month, 57 days, therefore, after the removal of the roof, that the earth was completely dried up. Then God commanded him to leave the ark with his family and all the animals; and so far as the latter were concerned, He renewed the blessing of the creation (Gen 8:17 cf. Gen 1:22). As the flood commenced on the 17th of the second month of the 600th year of Noah's life, and ended on the 27th of the second month of the 601st year, it lasted a year and ten days; but whether a solar year of 360 of 365 days, or a lunar year of 352, is doubtful. The former is the more probable, as the first five months are said to have consisted of 150 days, which suits the solar year better than the lunar. The question cannot be decided with certainty, because we neither know the number of days between the 17th of the seventh month and the 1st of the tenth month, nor the interval between the sending out of the dove and the 1st day of the first month of the 601st year.

Here is, 1. The ground dry (Gen 8:13), that is, all the water carried off it, which, upon the first day of the first month (a joyful new-year's-day it was), Noah was himself an eye-witness of. He removed the covering of the ark, not the whole covering, but so much as would suffice to give him a prospect of the earth about it; and a most comfortable prospect he had. For behold, behold and wonder, the face of the ground was dry. Note, (1.) It is a great mercy to see ground about us. Noah was more sensible of it than we are; for mercies restored are much more affecting than mercies continued. (2.) The divine power which now renewed the face of the earth can renew the face of an afflicted troubled soul and of a distressed persecuted church. He can make dry ground to appear even where it seemed to have been lost and forgotten, Psa 18:16. 2. The ground dried (Gen 8:14), so as to be a fit habitation for Noah. Observe, Though Noah saw the ground dry the first day of the first month, yet God would not suffer him to go out of the ark till the twenty-seventh day of the second month. Perhaps Noah, being somewhat weary of his restraint, would have quitted the ark at first; but God, in kindness to him, ordered him to stay so much longer. Note, God consults our benefit rather than our desires; for he knows what is good for us better than we do for ourselves, and how long it is fit our restraints should continue and desired mercies should be delayed. We would go out of the ark before the ground is dried: and perhaps, if the door be shut, are ready to remove the covering, and to climb up some other way; but we should be satisfied that God's time of showing mercy is certainly the best time, when the mercy is ripe for us and we are ready for it.

8:13 On the first day of the new year, ten and a half months after the flood began: This was two months after the peaks of the mountains first became visible (8:5).
