v. 7. And Noah went in, and his sons and his wife and his sons' wives with him, into the ark, because of the waters of the Flood. The members of Noah's household were thus one with him in faith and in obedience, for which reason they all, unlike Lot's wife, were saved in the catastrophe from the waters of the Deluge, which destroyed all other men.
v. 8. of clean beasts, and of beasts that are not clean, and of fowls, and of every thing that creepeth upon the earth,
v. 9. there went in two and two unto Noah into the ark, the male and the female, as God had commanded Noah. It was not a mere presentiment of coming danger that prompted the animals to gather about Noah, the clean and the unclean mammals, birds, and reptiles, neither was it a matter of instinct only, but it happened thus by God's arrangement, and it was He that commanded the animals to assemble at the place where the ark stood ready for occupancy. By pairs they entered into the ark under the direction of Noah, who thus fulfilled the command of God.
v. 10. And it came to pass after seven days that the waters of the Flood were upon the earth. Exactly according to the prediction of God, on the seventh day after His final command to Noah, the Flood came upon the earth. God's promises, whether they concern a blessing or a punishment, can never fail of fulfillment. It is a part of true wisdom in the believers to rely implicitly in His Word.
