'Ten' in the Bible

“Please, test your servants for ten days, and let us be given some vegetables to eat and water to drink.

So the man listened to them in this matter and tested them for ten days.

At the end of ten days it seemed that they were looking better and healthier than all the young men who ate the king’s finest food.

In every matter of wisdom and understanding about which the king consulted them, he found them ten times better than all the [learned] magicians and enchanters (Magi) in his whole realm.

In the days of those [final ten] kings the God of heaven will set up a kingdom that will never be destroyed, nor will its sovereignty be left for another people; but it will crush and put an end to all these kingdoms, and it will stand forever.

After this I kept looking in the night visions, and behold, [I saw] a fourth beast (the Roman Empire), terrible and extremely strong; and it had huge iron teeth. It devoured and crushed and trampled down what was left with its feet. It was different from all the beasts that came before it, and it had ten horns (ten kings).

“A river of fire was flowingAnd coming out from before Him;A thousand thousands were attending Him,And ten thousand times ten thousand were standing before Him;The court was seated,And the books were opened.

and the meaning of the ten horns (kings) that were on its head and the other horn which came up later, and before which three of the horns fell, specifically, that horn which had eyes and a mouth that boasted great things and which looked larger than the others.

As for the ten horns, out of this kingdom ten kings will arise; and another will arise after them, and he will be different from the former ones, and he will subdue three kings.
