From Religious Folk Songs of the Negro, new edition (1920; rpt. AMS, 1973, p. 175):

REIGN, MASSA JESUS

Chorus:
O reign, O reign, O reign, my Saviour,
Reign, Massa Jesus, reign.
O reign salvation in my soul,
Reign, Massa Jesus, reign.

Solo:
1. I never shall forget that day,
(Chorus: Reign, Massa Jesus, reign.)
When Jesus washed my sins away,
(Chorus: Reign, Massa Jesus, reign.)

2. I look'd at my hands and my hands look'd new,
I look'd at my feet and they look'd so too,

3. I never felt such love before,
Saying, "Go in peace and sin no more,"
