'People of God' in the Bible

The chiefs of all the people, even of all the tribes of Israel, took their stand in the assembly of the people of God, 400,000 foot soldiers who drew the sword.

The woman said, “Why then have you planned such a thing against the people of God? For in speaking this word the king is as one who is guilty, in that the king does not bring back his banished one.

So there remains a Sabbath rest for the people of God.

choosing rather to endure ill-treatment with the people of God than to enjoy the passing pleasures of sin,

for you once were not a people, but now you are the people of God; you had not received mercy, but now you have received mercy.
