'Classes' in the Bible

There went out to him people of all classes from Judaea, and the inhabitants of Jerusalem of all ranks, and were baptized by him in the river Jordan, making open confession of their sins.

The Law and the Prophets continued until John came: from that time the Good News of the Kingdom of God has been spreading, and all classes have been forcing their way into it.

To him people of all classes paid attention, declaring, "This man is the Power of God, known as the great Power."
