In the six hundredth year of Noah's life, in the second month, on the seventeenth day of the month, on that day all the fountains of the great deep burst forth, and the windows of the heavens were opened. ¹² And rain fell upon the earth forty days and forty nights. ¹³ On the very same day Noah and his sons, Shem and Ham and Japheth, and Noah's wife and the three wives of his sons with them entered the ark, ¹⁴ they and every beast, according to its kind, and all the livestock according to their kinds, and every creeping thing that creeps on the earth, according to its kind, and every bird, according to its kind, every winged creature. ¹⁵ They went into the ark with Noah, two and two of all flesh in which there was the breath of life. ¹⁶ And those that entered, male and female of all flesh, went in as God had commanded him.  And the Lord shut him in.
