Ambrose of Milan, on Isa 49:2

“And he hath made my mouth like a sharp sword: in the shadow of his hand he hath protected me, and hath made me as a chosen arrow: in his quiver he hath hidden me.”

“Make for yourself, O man, a case; stripping off the old man with his actions, put on the new. Your case, your sheath, is Christ, who protects and hides you in the evil day. Do you want to know why the case is protection? My quiver, He says, protected him. Therefore, your case is faith: fill it with the good scents of your virtues; that is, chastity, mercy, and justice, and in it, enter completely fragrant with the sweet scent of excellent deeds of faith.”
