upp og niðr ‘up and down’: The angels descended from heaven to earth, and then went up again. Cf. Gen. XXVIII.12 and Stjórn (Unger 1862, 169): Þar medr sá hann i suefininum ganga guds engla upp eptir stiganum ok nidr ‘Therewith he saw in his sleep the angels of God going up by means of a ladder and down [again]’ and Luke II.15: … ut discesserunt ab eis angeli in caelum … ‘... after the angels departed from them into heaven ...’. Cf. 1/6, uppi ok niðri ok þar í miðju. Several mss have uppi og niðri in this l. too (so Skj B and Skald).
