'Five' in the Bible

And they were not permitted to kill anyone, but to torment for five months; and their torment was like the torment of a scorpion when it stings a man.

They have tails like scorpions, and stings; and in their tails is their power to hurt men for five months.

and they are seven kings; five have fallen, one is, the other has not yet come; and when he comes, he must remain a little while.
