Genesis 7:12

12 The rain fell on the earth forty days and forty nights.

Genesis 7:12 In-Context

10 And after seven days the waters of the flood came on the earth.
11 In the six hundredth year of Noah's life, in the second month, on the seventeenth day of the month, on that day all the fountains of the great deep burst forth, and the windows of the heavens were opened.
12 The rain fell on the earth forty days and forty nights.
13 On the very same day Noah with his sons, Shem and Ham and Japheth, and Noah's wife and the three wives of his sons entered the ark,
14 they and every wild animal of every kind, and all domestic animals of every kind, and every creeping thing that creeps on the earth, and every bird of every kind—every bird, every winged creature.
