CHAPTER 7 Jan. 4 
The Preparations for the Flood 
Yahweh said to Noah, Come with all of your household into the ship, for I have seen your righteousness before Me in this generation. 2You shall take seven pairs of every clean animal with you, the male and his female. Of the animals that are not clean, take two, the male and his female. 3Also of the birds of the sky, seven and seven, male and female, to keep seed alive on the surface of all the earth. 4In seven days, I will cause it to rain on the earth for forty days and forty nights. Every living thing that I have made, I will destroy from the surface of the ground. 5Noah did everything that Yahweh commanded him. 6Noah was six hundred years old when the flood of waters came on the land. 7Noah went into the ship with his sons, his wife, and his sons’ wives, in the face of the floodwaters. 8Clean animals, animals that are not clean, birds, and everything that creeps on the ground 9went by pairs to Noah into the ship, male and female, as God commanded Noah. 10It happened after the seven days that the waters of the flood came on the earth. 11In the six hundredth year of Noah’s life, in the second month, on the seventeenth day of the month, on the same day all the fountains of the great deep were burst open, and the sky’s windows were opened. 12The rain was on the earth forty days and forty nights.
The Flood 
13In the same day Noah, and Shem, Ham, and Japheth, the sons of Noah, and Noah’s wife, and the three wives of his sons with them, entered into the ship; 14they, and every animal after its kind, all the livestock after their kind, every creeping thing that creeps on the earth after its kind, and every bird after its kind, every bird of every sort. 15They went to Noah into the ship, by pairs of all flesh with the breath of life in them. 16Those who went in, went in male and female of all flesh, as God commanded him; and Yahweh shut him in. 17The flood was forty days on the earth. The waters increased, and lifted up the ship, and it was lifted up above the earth. 18The waters prevailed, and increased greatly on the earth; and the ship floated on the surface of the waters. 19The waters prevailed exceedingly on the earth. All the high mountains that were under the whole sky were covered. 20The waters prevailed fifteen cubits upward, and the mountains were covered. 21All flesh died that moved on the earth, including birds, livestock, animals, every creeping thing that creeps on the earth, and every man. 22All in whose nostrils was the breath of the spirit of life, of all that was on the dry land, died. 23Every living thing was destroyed that was on the surface of the land, including man, livestock, creeping things, and birds of the sky. They were destroyed from the land. Only Noah was left alive, and those who were with him in the ship. 24The waters prevailed on the earth one hundred and fifty days.

Commentary

7:1 All your household- his entire family consisted of his three sons. He therefore had no daughters and it would seem that his sons had no children. This tiny family size must be significant- for in those long lived ages, most women would have likely had over 50 children. Again, it was the small, broken and despised who were chosen of God. It seems that Noah's daughters in law only started bearing after the flood. 
7:7  In the face of-   seems to imply that he waited until the very last minute. It seems this was not due to any lack of faith, but rather because of the urgency and desperation he felt in appealing to others to come into the ark with him. He truly was a remarkable “preacher of righteousness “ (2 Pet. 2:5). Our knowledge of this world’s future means that as we walk the streets and mix with men and women, our heart should cry out for them, no matter how they behave towards us, and there should be a deep seated desire for at least some of them to come to repentance and thereby avoid the judgments to come.
7:23 Noah only remained alive, and they that were with him- Noah is the focus of salvation, but in him and with him his family were saved. Likewise our salvation is by being “in Christ”.
