In Genesis, Noah waited seven days before sending the dove again after its first return. Genesis 8:10 says that he waited another seven days, then sent the dove from the ark for a second time.
The sequence has a repeated rhythm. Noah first sends the raven, then releases a dove that finds no resting place and returns. After waiting seven days, he sends the dove again, and it comes back with an olive leaf. Noah waits another seven days before releasing it once more.
This interval is separate from the forty days of rain and from the broader period during which the Flood waters remained high. The story includes several different time spans, so identifying which action each number describes is essential. Here, seven days refers specifically to Noah’s wait between dove releases.
