Azizi, I slipped a cog there; the line is used in the first verse of the song as sung by the Jubilee Singers in the 1880's. I have been thinking too much about sailors' songs and the chantey is running through my head. I still think "Dink's Song" is influenced by the chantey, not the religious song.

I have posted the version printed in Marsh, 1880's, "The Story of the Jubilee Singers," in thread 101413; I couldn't find the song in Mudcat. Great Getting-Up Morning
