17 The one who heeds instruction is on the way to life, but the one who rejects rebuke goes astray. 18 The one who conceals hatred utters lies, and the one who spreads slander is certainly a fool. 19 When words abound, transgression is inevitable, but the one who restrains his words is wise. 20 What the righteous say is like the best silver, but what the wicked think is of little value. 21 The teaching of the righteous feeds many, but fools die for lack of sense.
6 Some people keep silent because they have nothing to say, while others keep silent because they know when to speak. 7 The wise remain silent until the right moment, but a boasting fool misses the right moment. 8 Whoever talks too much is detested, and whoever pretends to authority is hated. 9 There may be good fortune for a person in adversity, and a windfall may result in a loss. 10 There is the gift that profits you nothing, and the gift to be paid back double.
