TSK · Genesis 7:12

For in seven days I will cause it to rain on the earth for forty days and forty nights, and I will wipe from the face of the ground every living thing that I have made.”

Moses went into the cloud when he went up the mountain, and Moses was on the mountain forty days and forty nights.

Then I again fell down before the LORD for forty days and nights; I ate and drank nothing because of all the sin you had committed, doing such evil before the LORD as to enrage him.

So he got up and ate and drank. That meal gave him the strength to travel forty days and forty nights until he reached Horeb, the mountain of God.
