Barnes' Notes
Cease from anger - That is, in reference to the fact that there are wicked people, and that they are permitted to carry out their plans. Do not allow your mind to be excited with envious, fretful, wrathful, or murmuring feelings against God because he bears patiently with them, and because they are allowed a temporary prosperity and triumph. Be calm, whatever may be the wickedness of the world. The supreme direction belongs to God, and he will dispose of it in the best way.
And forsake wrath - That is, as above, in regard to the existence of evil, and to the conduct of wicked men.
Fret not thyself in any wise - See Psalms 37:1. Let the mind be entirely calm and composed.
To do evil - So as to lead you to do evil. Do not allow your mind to become so excited that you will indulge in harsh or malignant remarks; or so as to lead you to do wrong to any man, however wicked he may be. See always that you are right, whatever others may be, and do not allow their conduct to be the means of leading you into sin in any form. Look to your own character and conduct first.
