'Seven Times' in the Bible

Then he returned, and walked in the house to and fro; and went up, and stretched himself upon him: and the child sneezed seven times, and the child opened his eyes.

And Elisha sent a messenger to him, saying, Go and wash in Jordan seven times, and thy flesh shall come again to thee, and thou shalt be clean.

Then he went down, and dipped himself seven times in Jordan, according to the saying of the man of God: and his flesh came again like the flesh of a little child, and he was clean.
