'Seven' in the Bible

And in that day seven women will take hold of one man, saying, “We will eat our own food and wear [and provide] our own clothes; only let us be called by your name; take away our shame [of being unmarried].”

And the Lord will utterly destroyThe tongue of the Sea of Egypt;And with His scorching windHe will wave His hand over the River;He will strike and divide it into seven channelsAnd make [it possible for] people [to] walk over in sandals.

The light of the full moon will be like the light of the sun, and the light of the sun will be seven times brighter, like the light of seven days [concentrated in one], in the day the Lord binds up the fracture of His people and heals the wound He has inflicted [because of their sins].
