The source for Park New Choir is very likely Hampton Institute's Religious Folk Songs of the Negro (new edition, 1920; AMS, 1973, p. 166). Another version is in Emily Hallowell's Calhoun Platation Songs (1901, 1907; AMS, 1976, p. 74):

I KNOW THE LORD HAS LAID HIS HANDS ON ME
(from Fisk Jubilee Collection)

    O, I know de Lord, I know de Lord,
    I know de Lord ha' laid His hands on me.
    O I know de Lord, I know de Lord,
    I know de Lord ha' laid His hands on me.

(Solo) My Lord done jus' what he say,
(Cho.) I know de Lord ha' laid His hands on me.
(Solo) Heal de sick an' raise de dead,
(Cho.) I know de Lord ha' laid His hands on me.

Some seek de Lord but they don't seek Him right.
    I know de Lord ha' laid His hands on me.
Fool all day an' pray at night,
    I know de Lord ha' laid His hands on me.
          O, I know de Lord etc.

Ef ever you see de light befo',
    I know de Lord ha' laid His hands on me.
Jesus preaching to the poo'
    I know de Lord ha' laid His hands on me.
          O, I know de Lord etc.
