He(Cesario) is now in some commerce with my lady and will by and by depart.
If this letter move him not, his legs cannot. I'll give it to him.
Sir Toby collects the challenge to read too
Nay, let me alone for swearing.

Fabian indirectly insults Sir Andrew's letter
This letter will breed no terror in the youth(Cesario). So I will deliver his challenge by word of mouth, set upon Aguecheeck a noticeable report of valor and drive the gentleman into a most hideous opinion of his rage, and skill. This will so fright them both that they will kill one another by look.
