Proverbs 25:13-15

New International Version - UK

¹³ Like a snow-cooled drink at harvest time
    is a trustworthy messenger to the one who sends him;
    he refreshes the spirit of his master.
¹⁴ Like clouds and wind without rain
    is one who boasts of gifts never given.

¹⁵ Through patience a ruler can be persuaded,
    and a gentle tongue can break a bone.
