36. When did Noah enter the ark?
Seven days before the flood began.
And Noah went in, and his sons, and his wife, and his sons' wives
with him, into the ark....
And it came to pass after seven days, that the waters of the flood were upon the earth.
The day that the flood began.
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 fountains of the great
deep broken up, and the windows of heaven were opened.
And the rain was upon the earth forty days and forty nights.
In the selfsame day entered Noah, and Shem, and Ham, and Japheth, the sons of Noah, and Noah's wife, and the three wives of his sons with
them, into the ark. Genesis 7:11-13
