6 But soon the knights with their bright-burning blades 7 Broke their rude troops, and orders did confound,

rude > clumsy orders > [their] ranks

8 Hewing and slashing at their idle shades;

idle > empty shades > shadows

9 For though they bodies seem, yet substance from them fades.

fades > vanishes (cf. 105.15:5)

209.16

As when a swarme of Gnats at euentide
2 Out of the fennes of Allan do arise,
Their murmuring small trompets sounden wide,
4 Whiles in the aire their clustring army flies,
That as a cloud doth seeme to dim the skies;
6 Ne man nor beast may rest, or take repast,
For their sharpe wounds, and noyous iniuries,
8 Till the fierce Northerne wind +with+ blustring blast
Doth blow them quite away, and in the Ocean cast.
