Genesis 7:12 Meaning and Commentary

Genesis 7:12

And the rain was upon the earth forty days and forty nights,
&c.] So long it was falling upon it, after the windows of heaven were opened. Aben Ezra would have it, that all things were in such confusion, during the flood, that there was no difference between day and night, since, it is said, "day and night shall not cease any more"; and that after the waters ceased, then Noah knew that forty days and nights had passed, for God had revealed this secret to him; but the text seems more to make against him than for him.

Genesis 7:12 In-Context

10 And it cometh to pass, after the seventh of the days, that waters of the deluge have been on the earth.
11 In the six hundredth year of the life of Noah, in the second month, in the seventeenth day of the month, in this day have been broken up all fountains of the great deep, and the net-work of the heavens hath been opened,
12 and the shower is on the earth forty days and forty nights.
13 In this self-same day went in Noah, and Shem, and Ham, and Japheth, sons of Noah, and Noah's wife and the three wives of his sons with them, unto the ark;
14 they, and every living creature after its kind, and every beast after its kind, and every creeping thing that is creeping on the earth after its kind, and every fowl after its kind, every bird -- every wing.
