If I could'nt say a word

[dwh]

the song only contained four veruses

if I could 'nt say a word, it was repeated two -three times
I'll just wave my hands

I am talking about Jesus, Repeated two-three times
He's a friend of mine
My dad used to sing this song I had forgotten it until recently, I attended the funeral of a close family friend and it was song
I began to wonder if it was a true song or part of some other song

If anyone one knows the songs I am talking about I would appreciate the lyrics and some background information
