Seven days after the issue of the command the rain is to commence, and continue for forty days and nights without ceasing. "Every standing thing" means every plant and animal on the land.

For yet seven days - God spoke these words probably on the seventh or Sabbath day, and the days of the ensuing week were employed in entering the ark, in embarking the mighty troop, for whose reception ample provision had been already made.

Forty days - This period became afterwards sacred, and was considered a proper space for humiliation. Moses fasted forty days, Deuteronomy 9:9, Deuteronomy 9:11; so did Elijah, 1 Kings 19:8; so did our Lord, Matthew 4:2. Forty days' respite were given to the Ninevites that they might repent, Jonah 3:4; and thrice forty (one hundred and twenty) years were given to the old world for the same gracious purpose, Genesis 6:3. The forty days of Lent, in commemoration of our Lord's fasting, have a reference to the same thing; as each of these seems to be deduced from this primitive judgment.

For yet seven days,.... Or one week more, after the above orders were given, which, the Jews say, were for the mourning at Methuselah's death; others, that they were an additional space to the one hundred and twenty given to the old world for repentance; in which time some might truly repent, finding that the destruction of the world was very near, and who might be saved from everlasting damnation, though not from perishing in the flood: but it rather was a space of time proper for Noah to have, to settle himself and family, and all the creatures in the ark, and dispose of everything there, in the best manner, for their sustenance and safety:

and I will cause it to rain upon the earth forty days and forty nights: this was not an ordinary but an extraordinary rain, in which the power and providence of God were eminently concerned, both with respect to the continuance of it, and the quantity of water that fell:

and every living substance that I have made will I destroy from off the face of the earth: not every substance that has a vegetative life, as plants, herbs, and trees, which were not destroyed, see Genesis 8:11 but every substance that has animal life, as fowls, cattle, creeping things, and men.

For yet seven days, and I will cause it to rain upon the earth forty days and forty nights; and every living substance that I have made will I destroy from off the face of the earth.

7:4 Yet seven days and I will cause it to rain - It shall be seven days yet before I do it, After the 120 years were expired, God grants them a reprieve of seven days longer, both to shew how slow he is to anger, and to give them some farther space for repentance. But all in vain; these seven days were trifled away after all the rest, they continued secure until the day that the flood came. While Noah told them of the judgment at a distance, they were tempted to put off their repentance: but now he is ordered to tell them that it is at the door; that they have but one week more to turn them in, to see if that will now at last awaken them to consider the things that belong to their peace. But it is common for those that have been careless for 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 seven days of their sickness, when they see it approaching, their hearts being hardened by the deceitfulness of sin.

destroy: Heb. blot out

4. For yet seven days-A week for a world to repent! What a solemn pause! Did they laugh and ridicule his folly still? He whose eyes saw and whose heart felt the full amount of human iniquity and perverseness has told us of their reckless disregard (Lu 17:27).

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.
