Proverbs 25:13-15

Common English Bible

¹³ Like the coolness of snow on a harvest day
    are reliable messengers to those who send them;
    they restore the life of their master.
¹⁴ People who brag about a gift never given
    are like clouds and wind that produce no rain.
¹⁵ A commander can be persuaded with patience,
    and a tender tongue can break a bone.
