[4] færiz ‘is moved’: The expression færa (older fœra) ór stað ‘to move (sth.) from its place’ requires a direct object if in active voice, and gjálfr ‘the surge’ may be either acc. or nom. Most mss read færir ‘moves’ 3rd pers. sg. pres. tense, but sense requires a passive construction, hence the preference here (so also Frið 1901, 16) for m. v. færiz. At least one younger ms., ÍB65ˣ, has the m. v. form. Finnur Jónsson (Skj B; so also Skald) keeps færir, but translates with a passive construction: gamle galdre volder nu det, at havet bevæges stærkt ‘old spells now cause the sea to be strongly moved’. There is, however, no evidence of færa used impersonally with an acc. object.
