The one on the Border Radio CD is a shortened version. The Carters first recorded it on 15 February 1929. Sara thought it may have come from an old hymn book, but none has been found. Here is my best shot at it. Dale or someone else may be able to make any necessary corrections:

GOD GAVE NOAH THE RAINBOW SIGN
(Unknown)

I've got a home in that rock don't you see
I've got a home in that rock don't you see
I've got a home in that rock just beyond the mountain top
Hide the Old Rock of Ages there for me

God gave Noah the rainbow sign don't you see
God gave Noah the rainbow sign don't you see
God gave Noah the rainbow sign no more water but fire next time
Hide the Old Rock of Ages there for me

Poor old Lazarus poor as I don't you see
Poor old Lazarus poor as I don't you see
Poor old Lazarus poor as I when he died he had a home on high
Hide the Old Rock of Ages there for me

East and west the fire will roll hide thou me
East and west the fire will roll hide thou me
East and west the fire will roll how will it be with my poor soul
Hide the Old Rock of Ages there for me

When this world is all on fire hide thou me
When this world is all on fire hide thou me
When this world's all on fire let thy bosom be my pillow
Hide the Old Rock of Ages there for me
