'Seven' in the Bible

"At that time, seven women will cling tightly to one man and will make him this offer: "We'll provide our own bread. We'll provide our own clothes. Just let us marry you so we won't be stigmatized anymore.'"

The LORD will totally destroy the gulf of the Sea of Egypt. He will sweep his hand over the Euphrates River with a violent wind, breaking it up into seven streams, and making a way for people to cross on foot.

Moreover, the light of the moon will be like the light of the sun, and the sun's light will be seven times brighter, like the light of seven full days, when the LORD binds up the bruises of his people and heals the wounds inflicted by his blow.
