From The Michigan University Song Book by Franklin Wagner (New York: Hinds, Noble & Eldredge, 1904) – where it appears with musical notation for 4 voices:

LULLABY.
English Version by Mrs. G. Federlein. Johannes Brahms.

Lullaby, my dear one,
The daylight is done;
The flowers so fair
Thy rest will now share.
Till tomorrow, oh, sleep,
While the angels watch keep.
Till tomorrow, oh, sleep,
While the angels watch keep.

Lullaby, my dear one,
The darkness has come;
In dreams shalt behold
Sweet stories of old.
With His love pure and mild
God shall guard thee, my child.
With His love pure and mild
God shall guard thee, my child.
