[2-3] harmi bura Jónakrs ‘by the pain of the sons of Jónakr [STONES]’: The kenning alludes to the heroic legend of Hamðir and Sǫrli, sons of Guðrún and her third husband Jónakr. Guðrún dispatches the brothers to take revenge against Jǫrmunrekkr for a brutal injustice against their half-sister, but their revenge fails because they refuse the aid of their half-brother Erpr, and kill him. Because they are impervious to metal weapons, they are killed with stones by Jǫrmunrekkr’s men (Bragi Rdr 5-6III; Hamð 25).
