'Seven' in the Bible

Then Nebuchadnezzar was filled with fury, and his facial expression changed toward Shadrach, Meshach, and Abed-nego. Then he gave a command that the furnace was to be heated seven times hotter than usual.

“Let his mind and nature be changed from a man’sAnd let an animal’s mind and nature be given to him,And let seven periods of time pass over him.

In that the king saw an angelic watcher, a holy one, descending from heaven and saying, “Cut the tree down and destroy it; but leave the stump with its roots in the earth, but with a band of iron and bronze around it in the new grass of the field, and let him be wet with the dew of heaven, and let him feed with the beasts of the field until seven periods of time pass over him,”

that you shall be driven from mankind and your dwelling place shall be with the beasts of the field; and that you be given grass to eat like the cattle and be wet with the dew of heaven; and seven periods of time shall pass over you, until you know [without any doubt] that the Most High [God] rules over the kingdom of mankind and He bestows it to whomever He desires.

and you will be driven away from mankind, and your dwelling place will be with the animals of the field. You will be given grass to eat like the cattle, and seven periods of time will pass over you until you know [without any doubt] that the Most High God rules over the kingdom of mankind and He bestows it on whomever He desires.”’

“But at the end of the days [that is, at the seven periods of time], I, Nebuchadnezzar, raised my eyes toward heaven, and my understanding and reason returned to me; and I blessed the Most High [God] and I praised and honored and glorified Him who lives forever,For His dominion is an everlasting dominion;And His kingdom endures from generation to generation.

So you are to know and understand that from the issuance of the command to restore and rebuild Jerusalem until [the coming of] the Messiah (the Anointed One), the Prince, there will be seven weeks [of years] and sixty-two weeks [of years]; it will be built again, with [a city] plaza and moat, even in times of trouble.

And he will enter into a binding and irrevocable covenant with the many for one week (seven years), but in the middle of the week he will stop the sacrifice and grain offering [for the remaining three and one-half years]; and on the wing of abominations will come one who makes desolate, even until the complete destruction, one that is decreed, is poured out on the one who causes the horror.”
