Judah

The 'city of Judah,' as in Isaiah 40:9, signifies the doctrine of love towards the Lord and love towards our neighbor.

Isaiah 40:9

⁹ You who tell good news to Zion, go up on a high mountain. You who tell good news to Jerusalem, lift up your voice with strength. Lift it up. Don't be afraid. Say to the cities of Judah, "Behold, your God!"
