'People of God' in the Bible

And the leaders of all the people, of all the tribes of Israel, presented themselves in the assembly of the people of God, four hundred thousand footmen that drew sword.

And the woman said, Why then have you thought such a thing against the people of God? For the king speaks this thing as one who is at fault, in that the king does not bring his banished one home again.

So then there remains a rest to the people of God.

choosing rather to suffer affliction with the people of God than to enjoy the pleasures of sin for a time,

you who then were not a people, but now the people of God, those not pitied then, but now pitied.
