I had to consult the Google. It’s actually from an African Spiritual which fits since I sang it in Highschool chorus. Can’t confirm any Bible references.

There is a balm in Gilead
To make the wounded whole;
There is a balm in Gilead
To heal the sin-sick soul.
Some times I feel discouraged,
And think my work’s in vain,
But then the Holy Spirit
Revives my soul again.
(Chorus)

If you cannot sing like angels,
If you can’t preach like Paul,
You can tell the love of Jesus,
And say He died for all.
