Charles Ellicott Commentary Proverbs 25:23

"The north wind bringeth forth rain: So doth a backbiting tongue an angry countenance." — Proverbs 25:23 (ASV)

The north wind driveth away rain.— The marginal rendering is probably more correct: “The north wind bringeth forth rain;” but as this seems to be opposed to Job 37:22, it has been thought that the north-west, which is a rainy wind, must be intended here.

So doth an angry countenance a backbiting tongue.—Rather, So doth a backbiting tongue (bring forth, or cause) troubled faces.
