The lance which pierces the foe before he gets near symbolizes foresight. [Raymond] Lull began his discussion of this subject by pointing out that every article of priestly vestments had its symbolic significance.

This signifies that knights should use the sword to slay foes of the cross. The sword has two edges to remind the knight that he should defend chivalry and justice.
