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

(Odkazy: Apocalypse Explained 850)

Food and drink in the Bible represent the desire to be loving and the understanding of how to be loving, gifts that flow from the Lord and sustain life. Since a table is where we receive these gifts and make them a part of us, it follows that tables in the Bible represent receptacles of good things from the Lord, the places He can fill in our hearts and minds. In the contrary sense, tables can also represent receptacle of evil from hell; we can allow ourselves to be filled with those as well.
