There are interesting variations in the last stanza:

And away on the mountain so high,
The last one that ever might see,
While in his victorious, his hope was most glorious
He'd soon o'er the Jordan be free.
When his labor did cease, he departed in peace
And rested in the Heavens above.
Carter family 1929, also Dylan

And away on a mountain so high
The last that he ever did see
With Israel victorious, his hopes were most glorious
That soon all the Jordan be free
When his spirit did cease, he departed in peace
And rested in the Heavens above
Baez version, also Roy Acuff

Away on the mountain so high,
The last one that ever might be,
While he was victorious his hopes was so glorious
He stood o'er Jordan and preached.
Randolph, 1941

The Baez version seems to have been changed to reflect modern Zionist tendencies, nu?
