Genesis 7:24 Meaning and Commentary

Genesis 7:24

And the waters prevailed upon the earth one hundred and
fifty days.
] Which is to be reckoned not from the end of the forty days' rain, but from the beginning of the flood; for from the seventeenth day of the second month, when the fountains of the deep were broken up, and the windows of heaven were opened, unto the seventeenth day of the seventh month, when the ark rested on the mountains of Ararat, and the waters decreased, were just five months, or one hundred and fifty days; until which time the waters increased yet more and more, even after the forty days' rain; so that it seems there was a continual rain afterwards, as Aben Ezra observes, though not so vehement; or otherwise it is not so easy to account for the increase of the waters.

Genesis 7:24 In-Context

22 All men, and all things in which the breathing of life was in [the] earth, were dead. (And all men, and all the things on the earth in which was the breath of life, died.)

23 And God did away all the substance that was on [the] earth, from man till to beast, as well a creeping beast, as the birds of (the) heaven(s); and those were done away from [the] earth. Forsooth Noe dwelled alone, and they that were with him in the ship. (And so God did away all the life that was on the earth, from man unto beasts, and reptiles, and the birds of the air, they were all done away from the earth. And only Noah, and those who were with him in the ship, remained alive.)

24 And the waters of the great flood over-went the earth an hundred and fifty days. (And the waters of the great flood went over the earth for a hundred and fifty days.)
