John Trapp on Proverbs 12:16

Verſ. 16. A fools wrath is preſently known] Hee hath no power over his paſſions. Hence [non-Latin text not transcribed] a fool, and [non-Latin text not transcribed] ſuddenly, raſhly, is from the ſame root. Like Tow, hee is ſoon kindled, like a pot, hee ſoon boyls, and like a candle whoſe tallow is mixt with brine, as ſoon as lighted hee ſpits up and down the room. A fool uttereth all his minde, Prov. 29.11. The Septuagint render it, All his anger. [non-Latin text not transcribed]. For, as the Hebrews well note in a Proverb they have, A mans minde is ſooneſt diſcovered, bekis, bekos, becognos, in loculis, in poculis, in ira, in his purſe, in his drink, in his anger. See my Common-place of Anger.

But a wiſe man covereth ſhame] By concealing his wrath, or rather by ſuppreſſing it, when it would break forth to his diſgrace, or the juſt grief of another.Ovid. Ut fragilis glacies, occidit ira morâ. This was Sauls wiſdome, 1 Sam. 10.27. And Jonathans, when incenſed by his Fathers frowardneſs, hee went a ſhooting, 1 Sam. 12.35. And Ahaſhueroſh, when in a rage againſt Haman, hee walked into the Garden. The Philoſopher wiſhed Augustus when angry, to ſay over the Greek Alphabet; Ambroſe deſired an Angels Authority, Gal. 1.8. Theodoſius to repeat the Lords Prayer, before hee decreed any thing.
