MacLeod and Mees state that the opening lines of the charm correspond to the "Poetic Edda" poem "Sigrdrífumál", where the valkyrie Sigrdrífa provides runic advice, and that the meaning of the term "skag" is unclear, but a cognate exists in "Helgakviða Hundingsbana I" where Sinfjötli accuses Guðmundr of having once been a ""skass"-valkyrie". MacLeod and Mees believe the word means something like "supernatural sending", and that this points to a connection to the Ragnhild Tregagás charm, where a valkyrie is also "sent forth".
