Jennifer, It is too hard to read your tiny, jam-up print.
So I will excuse myself from this discussion.
Jesus is the only name our Savious had or has. It is not an OT name, for Jesus was of Grace. Paul was changed because now Saul was into Grace.
The real signifiance in these name changes is to show a change. they came from Law to Grace.
This is the only way to find salvation.
by law shall no flesh be justified.
