What does Genesis 8:5 mean?
The previous verse told us that the ark came to rest on the mountains of Ararat on a specific date: the seventeenth day of the seventh month of Noah's 600th year. The waters continued to steadily drain from the earth, but it still took until the first day of the tenth month for the tops of the mountains to become visible. That's about another two and a half months, or ten weeks.This is the third specific date given in the story of the flood. The date that land finally began to appear above the waters was significant enough to include in the official timeline. One important reason for including these specific dates and locations in the story of the flood is to let readers know that this was an historical event. The writer is clearly of the opinion that these events happened to real people in the real world. It wasn't meant to be understood as a myth that happened in times before memory, or as a mere parable in some fantasy world. God intended for the story of the flood to be believed and taken seriously.
