Be not hasty in your spirit to be angry: for anger rests in the bosom of fools.
All Commentaries on Ecclesiastes 7:9 Go To Ecclesiastes 7
John Cassian
AD 435
The deadly poison of anger has to be utterly rooted out from the inmost corners of our soul. For as long as this remains in our hearts and blinds with its hurtful darkness the eye of the soul, we can neither acquire right judgment and discretion nor gain the insight which springs from an honest gaze, or ripeness of counsel. Nor can we be partakers of life, or retentive of righteousness, or even have the capacity for spiritual and true light, “for,” says one, “mine eye is disturbed by reason of anger.” Nor can we become partakers of wisdom, even though we are considered wise by universal consent, for “anger rests in the bosom of fools.”
