'Continue' in the Bible

They have power given to them to seal up the sky, so that no rain may fall so long as they continue to prophesy; and power over the waters to turn them into blood, and to smite the earth with various plagues whenever they choose to do so.

And they are seven kings: five of them have fallen, and the one is still reigning. The seventh has not yet come, but when he comes he must continue for a short time.
