Of fowls also of the air by sevens, the male and the female; to keep seed alive upon the face of all the earth.

Matthew Henry's Concise Commentary

7:1-12 The call to Noah is very kind, like that of a tender father to his children to come in-doors when he sees night or a storm coming. Noah did not go into the ark till God bade him, though he knew it was to be his place of refuge. It is very comfortable to see God going before us in every step we take. Noah had taken a great deal of pains to build the ark, and now he was himself kept alive in it. What we do in obedience to the command of God, and in faith, we ourselves shall certainly have the comfort of, first or last. This call to Noah reminds us of the call the gospel gives to poor sinners. Christ is an ark, in whom alone we can be safe, when death and judgment approach. The word says, Come; ministers say, Come; the Spirit says, Come, come into the Ark. Noah was accounted righteous, not for his own righteousness, but as an heir of the righteousness which is by faith, Heb 11:7. He believed the revelation of a saviour, and sought and expected salvation through Him alone. Thus was he justified by faith, and received that Spirit whose fruit is in all goodness; but if any man have not the Spirit of Christ, he is none of his. After the hundred and twenty years, God granted seven days' longer space for repentance. But these seven days were trifled away, like all the rest. It shall be but seven days. They had only one week more, one sabbath more to improve, and to consider the things that belonged to their peace. But it is common for those who have been careless of their souls during the years of their health, when they have looked upon death at a distance, to be as careless during the days, the few days of their sickness, when they see death approaching; their hearts being hardened by the deceitfulness of sin. As Noah prepared the ark by faith in the warning given that the flood would come, so he went into it, by faith in this warning that it would come quickly. And on the day Noah was securely fixed in the ark, the fountains of the great deep were broken up. The earth had within it those waters, which, at God's command, sprang up and flooded it; and thus our bodies have in themselves those humours, which, when God pleases, become the seeds and springs of mortal diseases. The windows of heaven were opened, and the waters which were above the firmament, that is, in the air, were poured out upon the earth. The rain comes down in drops; but such rains fell then, as were never known before or since. It rained without stop or abatement, forty days and forty nights, upon the whole earth at once. As there was a peculiar exercise of the almighty power of God in causing the flood, it is vain and presumptuous to attempt explaining the method of it, by human wisdom.
