Answer:
Assuming that this is about "The Elfking" by Franz Schubert, the answer is that the opening lines of the poem describe a father and his son (riding on a horse). Therefore, the first stanza is:
Wer reitet so spät durch Nacht und Wind?
Es ist der Vater mit seinem Kind;
Er hat den Knaben wohl in dem Arm,
Er fasst ihn sicher, er hält ihn warm.
(Adaptation in English:
Who rides there so late through the night dark and drear?
The father it is, with is infant so dear;
He holdeth the boy tightly clasp'd in his arm,
He holdeth him safely, he keepeth his warm.)
