Day 4 is Noah. This is my 4 year old son's second favorite story in the bible at the moment. (The first favorite is the Creation story, but really, anything having to do with animals is tops in his book!)
Genesis 6:5-8, 13-22; 7:17, 23, 24; 8:1, 6-22
 And God seeing that the wickedness of men was great on the earth, and that all the thought of their heart was bent upon evil at all times,
 It repented him that he had made man on the earth. And being touched inwardly with sorrow of heart,  He said: I will destroy man, whom I have created, from the face of the earth, from man even to beasts, from the creeping thing even to the fowls of the air, for it repenteth me that I have made them.  But Noe found grace before the Lord.
 He said to Noe: The end of all flesh is come before me, the earth is filled with iniquity through them, and I will destroy them with the earth.  Make thee an ark of timber planks: thou shalt make little rooms in the ark, and thou shalt pitch it within and without.  And thus shalt thou make it: The length of the ark shall be three hundred cubits: the breadth of it fifty cubits, and the height of it thirty cubits.  Thou shalt make a window in the ark, and in a cubit shalt thou finish the top of it: and the door of the ark thou shalt set in the side: with lower, middle chambers, and third stories shalt thou make it.  Behold I will bring the waters of a great flood upon the earth, to destroy all flesh, wherein is the breath of life, under heaven. All things that are in the earth shall be consumed.  And I will establish my covenant with thee, and thou shalt enter into the ark, thou and thy sons, and thy wife, and the wives of thy sons with thee.  And of every living creature of all flesh, thou shalt bring two of a sort into the ark, that they may live with thee: of the male sex, and the female.  Of fowls according to their kind, and of beasts in their kind, and of every thing that creepeth on the earth according to its kind; two of every sort shall go in with thee, that they may live.
 Thou shalt take unto thee of all food that may be eaten, and thou shalt lay it up with thee: and it shall be food for thee and them.  And Noe did all things which God commanded him.
 And the flood was forty days upon the earth, and the waters increased, and lifted up the ark on high from the earth.
 And he destroyed all the substance that was upon the earth, from man even to beast, and the creeping things and fowls of the air: and they were destroyed from the earth: and Noe only remained, and they that were with him in the ark.  And the waters prevailed upon the earth a hundred and fifty days.
 And God remembered Noe, and all the living creatures, and all the cattle which were with him in the ark, and brought a wind upon the earth, and the waters were abated.
 And after that forty days were passed, Noe, opening the window of the ark which he had made, sent forth a raven: [Genesis 8:6] [Latin]  Which went forth and did not return, till the waters were dried up upon the earth.  He sent forth also a dove after him, to see if the waters had now ceased upon the face of the earth.  But she, not finding where her foot might rest, returned to him into the ark: for the waters were upon the whole earth: and he put forth his hand, and caught her, and brought her into the ark.  And having waited yet seven other days, he again sent forth the dove out of the ark.  And she came to him in the evening, carrying a bough of an olive tree, with green leaves, in her mouth. Noe therefore understood that the waters were ceased upon the earth.  And he stayed yet other seven days: and he sent forth the dove, which returned not any more unto him.  Therefore in the six hundredth and first year, the first month, the first day of the month, the waters were lessened upon the earth, and Noe opening the covering of the ark, looked, and saw that the face of the earth was dried.  In the second month, the seven and twentieth day of the month, the earth was dried.  And God spoke to Noe, saying:  Go out of the ark, thou and thy wife, thy sons, and the wives of thy sons with thee.  All living things that are with thee of all flesh, as well in fowls as in beasts, and all creeping things that creep upon the earth, bring out with thee, and go ye upon the earth: increase and multiply upon it.  So Noe went out, he and his sons: his wife, and the wives of his sons with him.  And all living things, and cattle, and creeping things that creep upon the earth, according to their kinds, went out of the ark.  And Noe built an altar unto the Lord: and taking of all cattle and fowls that were clean, offered holocausts upon the altar.  And the Lord smelled a sweet savour, and said: I will no more curse the earth for the sake of man: for the imagination and thought of man's heart are prone to evil from his youth: therefore I will no more destroy every living soul as I have done.  All the days of the earth, seedtime and harvest, cold and heat, summer and winter, night and day, shall not cease.
