'Seven' in the Bible

And seven women shall take hold of one man in that day, saying, Our own bread will we eat, and with our own garments will we be clothed; only let us be called by thy name; take away our reproach!

And Jehovah will utterly destroy the tongue of the Egyptian sea; and with his mighty wind will he shake his hand over the river, and will smite it into seven streams, and make men go over dryshod.

And the light of the moon shall be as the light of the sun, and the light of the sun shall be sevenfold, as the light of seven days, in the day that Jehovah bindeth up the breach of his people, and healeth the wound of their stroke.
