17   Whoever meddles in a quarrel not his own
    is like one who takes a passing dog by the ears.
18   Like a madman who throws firebrands, arrows, and death
19   is the man who deceives his neighbor
    and says, “I am only joking!”
20   For lack of wood the fire goes out,
    and where there is no whisperer, quarreling ceases.
21   As charcoal to hot embers and wood to fire,
    so is a quarrelsome man for kindling strife.
22   The words of a whisperer are like delicious morsels;
    they go down into the inner parts of the body.
23   Like the glaze covering an earthen vessel
    are fervent lips with an evil heart.
24   Whoever hates disguises himself with his lips
    and harbors deceit in his heart;
25   when he speaks graciously, believe him not,
    for there are seven abominations in his heart;
26   though his hatred be covered with deception,
    his wickedness will be exposed in the assembly.
27   Whoever digs a pit will fall into it,
    and a stone will come back on him who starts it rolling.
28   A lying tongue hates its victims,
    and a flattering mouth works ruin.
