[2] þrekfǫrluðum jarli ‘for the strength-failing jarl’: Sigvaldi, as is made clear in l. 6. The second element of this hap. leg. is the p. p. of fǫrla ‘grow weak, fail’ (CVC: förla); cf. Máni Lv 5/3III kraptr þinn fǫrlask ‘your strength is waning’. The variant þreklynduðum ‘strong-’ or ‘courageous-minded’ does not provide skothending, and R’s reading is the lectio difficilior and more precisely apt in context.
