Genesis 7:1 Then the LORD said to Noah, “Go into the ark, you and all your household, for I have seen that you are righteous before me in this generation. Take with you seven pairs of all clean animals, the male and his mate, and a pair of the animals that are not clean, the male and his mate, and seven pairs of the birds of the heavens also, male and female, to keep their offspring alive on the face of all the earth. For in seven days I will send rain on the earth forty days and forty nights, and every living thing that I have made I will blot out from the face of the ground.” And Noah did all that the LORD had commanded him. Noah was six hundred years old when the flood of waters came upon the earth. And Noah and his sons and his wife and his sons’ wives with him went into the ark to escape the waters of the flood. Of clean animals, and of animals that are not clean, and of birds, and of everything that creeps on the ground, two and two, male and female, went into the ark with Noah, as God had commanded Noah. And after seven days the waters of the flood came upon the earth.
Matthew 24:37-39 For as were the days of Noah, so will be the coming of the Son of Man. For as in those days before the flood they were eating and drinking, marrying and giving in marriage, until the day when Noah entered the ark, and they were unaware until the flood came and swept them all away, so will be the coming of the Son of Man.
Hebrews 11:7 By faith Noah, being warned by God concerning events as yet unseen, in reverent fear constructed an ark for the saving of his household. By this he condemned the world and became an heir of the righteousness that comes by faith.
Psalms 91:1-10 He who dwells in the shelter of the Most High will abide in the shadow of the Almighty. I will say to the LORD, “My refuge and my fortress, my God, in whom I trust.”
Proverbs 14:26 In the fear of the LORD one has strong confidence, and his children will have a refuge.
Proverbs 18:10 The name of the LORD is a strong tower; the righteous man runs into it and is safe.
Psalms 33:18-19 Behold, the eye of the LORD is on those who fear him, on those who hope in his steadfast love, that he may deliver their soul from death and keep them alive in famine.
2 Peter 2:5-9 if he did not spare the ancient world, but preserved Noah, a herald of righteousness, with seven others, when he brought a flood upon the world of the ungodly; if by turning the cities of Sodom and Gomorrah to ashes he condemned them to extinction, making them an example of what is going to happen to the ungodly; and if he rescued righteous Lot, greatly distressed by the sensual conduct of the wicked (for as that righteous man lived among them day after day, he was tormenting his righteous soul over their lawless deeds that he saw and heard); then the Lord knows how to rescue the godly from trials, and to keep the unrighteous under punishment until the day of judgment,
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. (Henry)
