As the cold of snow in the time of harvest, so is a faithful messenger to them that send him: for he refresheth the soul of his masters.
– Proverbs 25:13
The precise meaning of the image is treated variously by commentators, but the point of the proverb is clear from the last phrase. A faithful messenger is one who discharges his duty as appointed. There is a relation to the proverbs of speech in the sense that the messenger is faithful to relay the speech of his master. This would also be wise speech. The result is refreshing, or returning, the soul of his masters. Wisdom also contrasts the negative effects of an unfaithful messenger (Proverbs 13:17; 25:25; 26:6).
