Proverbs 25:13-15

¹³As the cold of snow in the time of harvest, so is a faithful messenger to him that sent him, for he refresheth his soul.

¹⁴As clouds, and wind, when no rain followeth, so is the man that boasteth, and doth not fulfill his promises.

¹⁵By patience a prince shall be appeased, and a soft tongue shall break hardness.
