3 Nor shall avail the wicked sorcery 4 Of false Pellitus, his purposes to break, 5 But him shall slay, and on a gallows bleak 6 Shall give the enchanter his unhappy hire;

hire > reward

7 Then shall the Britons, late dismayed and weak,

dismayed > defeated

8 From their long vassalage begin to respire,

respire > take relief; recover [hope, courage]; resurface to breathe

9 And on their paynim foes avenge their rankled ire.

paynim > pagan

Ne shall he yet his wrath so mitigate,
2 Till both the sonnes of Edwin he haue slaine,
Offricke and Osricke, twinnes vnfortunate,
4 Both slaine in battell vpon Layburne plaine,
Together with the king of Louthiane,
6 Hight Adin, and the king of Orkeny,
Both ioynt partakers of +their+ fatall paine:
8 But Penda, fearefull of like desteny,
Shall yield him selfe his liegeman, and sweare fealty.
