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

Isaiah 58:7-8
7
Isn't it to distribute your bread to the hungry, and that you bring the poor who are cast out to your house? When you see the naked, that you cover him; and that you not hide yourself from your own flesh?
8
Then your light shall break forth as the morning, and your healing shall spring forth speedily; and your righteousness shall go before you; the glory of Yahweh shall be your rear guard.
