'Seven Times' in the Bible

Elisha got up, went into the house, and paced back and forth. Then he went up and bent down over him again. The boy sneezed seven times and opened his eyes.

Then Elisha sent him a messenger, who said, “Go wash seven times in the Jordan and your flesh will be restored and you will be clean.”

So Naaman went down and dipped himself in the Jordan seven times, according to the command of the man of God. Then his skin was restored and became like the skin of a small boy, and he was clean.
