[All]: Cf. Vafþr 54/4-6, in which Óðinn asks the same question (differently worded, though the present l. 3 and Vafþr 54/4 are identical) to win a wisdom contest with the giant Vafþrúðnir (NK 55): hvat mælti Óðinn | áðr á bál stigi | siálfr í eyra syni? ‘what did Óðinn himself say into the ear of his son before he ascended the pyre?’.
