Therefore remove sorrow from your heart, and put away evil from your flesh: for childhood and youth are vanity.
All Commentaries on Ecclesiastes 11:10 Go To Ecclesiastes 11
Didymus the Blind
AD 398
In Scripture the spirit is continuously called “heart.” The passage therefore means: Even if we sometimes are caught up in anger, this “anger” should not be allowed into the “heart,” so that the anger does not become a permanent condition. And when suddenly a desire comes up in the part of the soul which deals with desire, this desire should not be transferred to the spirit and to the part of the soul that deals with reason. Otherwise it becomes a permanent condition and not just an affect or a precondition for this affect, but simply evil.… If “anger is banished from your heart,” you will not do evil through the members of your body. Whoever is caught by anger often fights and may even decide to kill. Thus, if you “banish anger from your heart,” then evil, which comes about through deeds, will vanish as well.
