5 And feathered with an unlucky quill;
unlucky > {Mischievous, malicious; causing misfortune}
6 The wicked steel stayed not, till it did light
light > strike, alight
7 In his left thigh, and deeply did it thrill:
thrill > pierce
8 Exceeding grief that wound in him empight,
grief > pain, suffering empight > implanted
9 But more that with his foes he could not come to fight.
