‘A fool's wrath is presently known: but a prudent man covereth shame.
…
‘A prudent man concealeth knowledge: but the heart of fools proclaimeth foolishness.’
—Proverbs 12:15,16,23
‘The fool hath said in his heart, There is no God. Corrupt are they, and have done abominable iniquity: there is none that doeth good.’
—Psalm 53:1
