+Which, those his cruell foes, that stand hereby+,
2 Making aduantage, to reuenge their spight,
Would him disarme, and treaten shamefully,

But you, faire Sir, whose honorable sight
6 Doth promise hope of helpe, and timely grace,
Mote I beseech to succour his sad plight,
8 And by your powre protect his feeble cace.
First praise of knighthood is, foule outrage to deface.
