Be not hasty in thy spirit to be angry: for anger resteth in the bosom of fools.
Be not hasty - passionate with excitement, bursting out in complaints against God, and impatient at adversity befalling thee, as Job was (Ecclesiastes 5:2; Psalms 37:1-2; Psalms 37:8). Contrast Lamentations 3:24-27.
Anger resteth in the bosom of fools. It is fools who give way to anger or impatience and fretfulness at the sight of the prosperity of the ungodly (Psalms 37:1; Psalms 37:8).
