Noah and his family and all the animals enter the ark. It rains for 40 days and 40 nights. 15 cubits upward the water rose, every living substance that wasn’t upon the ark was destroyed. The water remained on the face of the earth for a total of 150 days.
In other words:It rained a lot, Noah, his family and a bunch of animals survived this flood on the ark.
That the animals don’t come two by two. Clean beasts, whatever they are, came in sevens. Unclean beasts are two by two. (Genesis 7: 2) Birds got to come on by sevens too(Genesis 7: 3)
Random bit of useless information:
Noah was 600 years, two months and 17 days old when this happened. (Genesis 7:11)
Most annoying bit:
Be prepared for disaster, make sure you have enough food for everyone because it can be a while. (Genesis 7:24)
