Verse of the Week - Proverbs 25:23 - June 22

This comparison is meant to show that the consequence of attacking others verbally is as natural as the north wind bringing rain. There will not be a different result. 

The Benson Commentary has this to say about verse twenty-three,

Undoubtedly the north wind brings clouds and rain in some climates, and if, as some assert, it generally does so in Judea, as according to Aristotle it does in those parts of Africa which border on the Mediterranean sea, this interpretation ought certainly to be preferred. Either of them, however, shows the odious disposition and character of backbiters; and that they ought to be discountenanced and frowned upon by all that love their fellow-creatures, and wish peace to be promoted among men.

Backbiting does not promote love, or peace. It brings anger in the same way that the north wind brings rain (or storms).
