Thomas Aquinas

Fourth, the generals of wars who are usually more audacious and more prompt to speak, still did not dare to speak presumptuously and boisterously in his presence. So he says, "Generals governed their tongues," speaking plainly and humbly. Sometimes they were so awestruck that they did not dare to speak at all, and so he says, "and their tongues cleaved to the roof of their mouths," and made them incapable of speech.
