'Chosen Ones' in the Bible

Unless those days had been shortened, no flesh would have been saved. But for the sake of the chosen ones, those days will be shortened.

For there will arise false christs, and false prophets, and they will show great signs and wonders, so as to lead astray, if possible, even the chosen ones.

He will send out his angels with a great sound of a trumpet, and they will gather together his chosen ones from the four winds, from one end of the sky to the other.
