'People of God' in the Bible

The chiefs of all the people, even of all the tribes of Israel, presented themselves in the assembly of the people of God, four hundred thousand footmen who drew sword.

The woman said, "Why then have you devised 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 home again his banished one.

There remains therefore a Sabbath rest for the people of God.
