Fr. Timothy Gallagher discusses the Fourteenth Rule:
"Likewise, he (the enemy) behaves as a chief bent on conquering and robbing what he desires: for, as a captain and chief of the army, pitching his camp, and looking at the forces or defenses of a stronghold, attacks it on the weakest side, in like manner the enemy of human nature, roaming about, looks in turn at all our virtues, theological, cardinal and moral; and where he finds us weakest and most in need for our eternal salvation, there he attacks us and aims at taking us."
