'Seven Times' in the Bible

Then he came back, and after walking once through the house and back, he went up, stretching himself out on the child seven times; and the child's eyes became open.

And Elisha sent a servant to him, saying, Go to Jordan, and after washing seven times in its waters your flesh will be well again and you will be clean.

Then he went down seven times into the waters of Jordan, as the man of God had said; and his flesh became like the flesh of a little child again, and he was clean.
