'Seven' in the Bible

Then Nebuchadnezzar was filled with anger and the image of his face was changed {toward} Shadrach, Meshach and Abednego, [so he] {ordered and said} to heat up the one furnace seven times what was usual to heat [it] up.

Let his mind be changed from [that of a] human, and let [the] mind of an animal be given to him, and let seven times pass over him.

And [inasmuch] that the king saw [the] watcher, a holy [one] coming down from heaven and he said, "Cut down the tree and destroy it, but the stump of its root in the earth leave with a band of iron and bronze in the grass of the field, and let it be watered with the dew of heaven and [let] his lot [be] with [the] animals of the field {until seven times have passed over him}."

you will be driven away {from human society} and {you will dwell} with the animals of the field, and you will be caused to graze grass like the oxen {yourself}, and you will be watered with the dew of heaven, and seven [periods of] time will pass over you until that you have acknowledged that the Most High [is] sovereign over the kingdom of humankind, and {to whom he wills} he gives it.

and you will be driven away from {human society} and your dwelling [will be] with the animals of the field and they will cause you to graze [the] grass like oxen, and seven times will pass over you, until you acknowledge that the Most High [is] sovereign over the kingdom of humankind and that he gives it to whom he wills.'

And you must know and you must understand [that] from [the] time of the going out of [the] word to restore and build Jerusalem until [an] anointed [one]-- leader--[will be] {seven weeks and sixty-two weeks}; it will be restored and will be built [with] streets and moat, but {in a time of oppression}.
