Genesis 8:2-5

The fountains of the deep and the windows of the heavens were closed, the rain from the heavens was restrained, and the waters receded from the earth continually. At the end of 150 days the waters had abated, and in the seventh month, on the seventeenth day of the month, the ark came to rest on the mountains of Ararat. And the waters continued to abate until the tenth month; in the tenth month, on the first day of the month, the tops of the mountains were seen.
