17 Bread of deceit is sweet to a man; but after, his mouth will be full of sand.
18 Every purpose is put into effect by wise help: and by wise guiding make war.
19 He who goes about talking of the business of others gives away secrets: so have nothing to do with him whose lips are open wide.
20 If anyone puts a curse on his father or his mother, his light will be put out in the blackest night.
21 A heritage may be got quickly at first, but the end of it will not be a blessing.
