Apocalypse Revealed # 165
165. "'You have a few names even in Sardis.'" (3:4) This symbolically means that they also have among them some people who do have life in their worship.
A few names means, symbolically, some who are of such a character as now described, for a name symbolizes someone's character. That is because everyone in the spiritual world is named in accordance with his character (no. 81). The character of the people described now is that they have life in their worship.
Matthew 21:7-9
7
and brought the donkey and the colt, and laid their clothes on them; and he sat on them.

A very great multitude spread their clothes on the road. Others cut branches from the trees, and spread them on the road.
9
The multitudes who went before him, and who followed kept shouting, "Hosanna to the son of David! Blessed is he who comes in the name of the Lord! Hosanna in the highest!"
