I wondered if one could look at it as undefended - - in the sense of verja?

> Þá mælti Skarphéðinn: "Þú skalt gera að ekki Höskuldur því að þú

munt oft sendur einn saman óvarlega (?).

> Then Skarphéðin spoke: `You shall do nothing, Höskuld, because you

will often (be) sent (on errands) one alone (z) unwarily

"Unwarily" seems to jar a bit in the context; I see that MM & HP have
"without protection." Anthony Faulkes in his glossary to
Skáldskaparmál has "unwarily, unguardedly." Either of which would fit
the context there.
