Where did Herbert Warren Wind come up with the name "Amen Corner" for the Masters?

From a jazz recording. The tune in question was "Shoutin' in that Amen Corner." It was reminiscent of churchgoers responding to a fire and brimstone preacher.

"I felt that I should try to come up with some appropriate name for that far corner of the course where the critical action had taken place. The only phrase with the word 'corner' I could think of (outside of football's 'coffin corner' and baseball's 'hot corner') was the title of a song on an old Bluebird record."

Amen Corner is a nickname for a three-hole stretch of the Augusta National Golf Course. Iis where Rae's Creek intersects the 13th fairway, then along the front edge of the twelfth green and finally alongside the eleventh green.
