Did you know that souls of men after death wear clothes?

Moses wore clothes when he appeared with Christ.

Mat 17:3  And, behold, there appeared unto them Moses and Elias talking with him.

Since Elijah did not die I did not mention him above!

The souls under the alter were given clothes to put on.

Rev 6:9  And when he had opened the fifth seal, I saw under the altar the souls of them that were slain for the word of God, and for the testimony which they held:

Rev 6:10  And they cried with a loud voice, saying, How long, O Lord, holy and true, dost thou not judge and avenge our blood on them that dwell on the earth?

Rev 6:11  And white robes were given unto every one of them; and it was said unto them, that they should rest yet for a little season, until their fellowservants also and their brethren, that should be killed as they were, should be fulfilled.

So souls of men have substance, it is called a spirit body, an exact Xerox copy of the human body they had while alive on earth.
