I learned this as "Farewell My Friends" from the singing of Sally Rogers. I found it as "Parting Friends" with the exact words/tune in the Lomax's book American Ballads and Folk Songs, of 1934 with a note:

From Professor George Pullen Jackson's White Spirituals of the Southern Uplands...McCurry (editor of the Social Harp gives the song with the note "the author, when eight years old learned the air of this tune from Mrs cCatherine Penn. That was, therefore in the year 1829"

In researching spirituals & gospel songs, this is one of the very few pre-1900 songs I found with lyrics that exactly match what I've heard sung.
