Here’s a Freeman’s recording and
My best guess at the lyrics
https://www.youtube.com/watch?v=Svb07lM9Eik
You hear a voice throughout the land
You hear of trouble on every hand
You hear of crying. You hear of dying
Sometimes your vision may even get blurred
You hear of sickness; of pain and woe
You’d even cut your brother way down low
Before you give up Oh listen Sir
Ask your brother Have you Heard
Chorus
Oh have you heard about the God I know
He's got your situation in control
And have you heard He'll pardon you
And He'll walk with you until your journey's through
And have you heard He'll hear you now
And loose those demons that'll hold you so bound
He’s coming soon. Oh heed His word
Praise the Lord I’m glad I’ve heard
Well Israel stood on Jordan's sands
While the spies went out to search the land
When they returned with grapes divine
There's milk and honey and it's so fine
But the giants out there; so big and tall
While we like grasshoppers walk around so small
But Joshua with a godlike nerve said
You bunch of cowards! Have you heard?
