Do you know where the symbols of the Holy Spirit comes from?

We are learning to understand the Holy Spirit's symbols from the scriptures stories.

I know I can do this when I read and match the symbols of the Holy Spirit to the scripture stories.

The Holy Spirit has a lot of signs!

We are learning to understand the finger of God as a symbol of the Holy Spirit.
I know I can do this when I describe how the Holy Spirit worked through the finger of God to guide Moses.
