An appropriate word.
v.11-12 A good word. An appropriate word, spoken at the right time, is like golden apples on a silver tray. A wise reprover, offering valid criticism, is to a listening ear like golden jewelry. That is, it is wise to listen to timely criticism and advice (15:31).
v.13 Trustworthy messengers. A trustworthy messenger is like a cold snow on a hot summer day, cooling and refreshing the one who sent him. Also 13:17.
v.14 Promises, promises. In an agrarian society where rain is rare, it is a great disappointment when storm clouds bring no rain. The proverb likens this to a man who promises a gift but doesn’t deliver. Jude 12 applies this image to false teachers.
v.15 Break a bone. With patience a ruler may be persuaded and a soft tongue will break a bone (i.e., stiff opposition can be broken down). See 15:1.
v.16-17 Moderation. Honey in moderation is good (v.27, 24:13-14) but too much can cause you to vomit, likewise don’t visit your neighbor too often or he will come to hate you. Familiarity breeds contempt. Too much of a good thing will have negative consequences.
v.18-20 Liar, treacherous, insensitive. A series of three proverbs about three types of men. (1) A man who tells lies about his neighbor is like a sharp arrow that does much damage. (2) Trusting a treacherous man in a time of trouble is like a bad tooth. (3) He who sings to a heavy heart is like vinegar on soda.
