Ge 7:1
7:1 And the LORD said unto Noah, Come thou and all thy house
    into the ark; for thee have I seen {a} righteous before me
    in this generation.

    (a) In respect to the rest of the world, and because he had
        a desire to serve God and live uprightly.

Ge 7:2
7:2 Of every {b} clean beast thou shalt take to thee by sevens,
    the male and his female: and of beasts that [are] not clean
    by two, the male and his female.

    (b) Which might be offered in sacrifice, of which six were
        for breeding and the seventh for sacrifice.

Ge 7:9
7:9 There {c} went in two and two unto Noah into the ark, the
    male and the female, as God had commanded Noah.

    (c) God compelled them to present themselves to Noah, as
        they did before to Adam, when he gave them names,
        Ge 2:19.

Ge 7:11
7:11 In the six hundredth year of Noah's life, in the second
     month, the seventeenth day of the month, the same day were
     all the {e} fountains of the great deep broken up, and the
     windows of heaven were opened.

     (e) Both the waters in the earth overflowed and also the
         clouds poured down.

Ge 7:15
7:15 And they went in unto Noah into the ark, two and two {f} of
     all flesh, wherein [is] the breath of life.

     (f) Every living thing that God would have be preserved on
         earth, came into the ark to Noah.

Ge 7:16
7:16 And they that went in, went in male and female of all
     flesh, as God had commanded him: and the LORD {g} shut him
     in.

     (g) So that God's secret power defended him against the
         rage of the mighty waters.

Ge 7:23
7:23 And every living substance was destroyed {h} which was upon
     the face of the ground, both man, and cattle, and the
     creeping things, and the fowl of the heaven; and they were
     destroyed from the earth: and Noah only {i} remained
     [alive], and they that [were] with him in the ark.

     (h) That is, by God.
     (i) Learn what it is to obey God only, and to forsake the
         multitude, 1Pe 3:20.
