'Seven Times' in the Bible

And he returned and walked in the house to and fro. And he went up and stretched himself on him. And the boy sneezed seven times, and the boy opened his eyes.

And Elisha sent a messenger to him, saying, Go and wash in Jordan seven times, and your flesh shall come to you, and you shall be clean.

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