The Faithful Messenger.
Refreshing The Soul.

25:13 Like the cold of snow in the time of harvest Is a faithful messenger to those who send him, For he refreshes the soul of his masters.

A faithful messenger does not necessarily bring welcome news.
He brings the news his masters require, and they are refreshed by it.
When a doctor tells someone he has cancer, this is important news that can be judiciously acted on.
I thank those who have corrected me in the past.
Even when it was not well received, it was needed for my guidance.
