Genesis 7:12 Meaning and Commentary

Genesis 7:12

And the rain was upon the earth forty days and forty nights,

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.
