Proverbs 13:17  A wicked messenger falls into mischief: but a faithful ambassador is health. 

‘A wicked messenger falls into mischief: but a faithful ambassador is health.’ A wicked messenger fails to carry out his duty, but a righteous one brings honour and safety to his king.

Five kinds of words: Appropriate words – words that come naturally, that run smoothly as if upon wheels, that are not forced, and that are without design to hurt are like apples of gold upon carvings of silver (25:11). Reproving words – words of a wise reprover to an obedient ear are like the most beautiful and cherished ornaments of fine gold to a refined and beautiful woman (25:12). Refreshing words – words of a faithful messenger are as refreshing and satisfying as a drink cooled by the snow in the heat of the harvest labour (25:13). Vain words – words of the boaster are as disappointing as clouds without rain (25:14). Kind words – by words of kindness, understanding, and longsuffering a judge is persuaded – as easily as a soft answer overcomes obstinacy in others (25:15).
