Oh, also I have transcribed the last verse (of three) in the Peggy and Penny Seeger rendition. The first verse is identical to the one you just posted (Poston)

The second is substantially the same as the fourth verse in Jackson.

The last is:

To teach us humility, all this was done
Then learn we from hence haughty pride for to shun
A manger's his cradle who came from above
The Great God of Mercy, of peace and of love
