Holman's Bible Dictionary . . . .
Human wrath is always suspect.
We hanged our harps upon the willows in the midst thereof. If I forget thee, O Jerusalem, let my right hand forget her cunning. Raze it, raze it, even to the foundation thereof. 9 Happy shall he be, that taketh and dasheth thy little ones against the stones. To realize this freedom from the domination of wrath, the gracious work of the Holy Spirit is needed to sanctify and cleanse the heart of the attitudes and feelings of wrath and anger.
