Let all bitterness. He again condemns anger; but, on the present occasion, views in connection with it those offenses by which it is usually accompanied, such as noisy disputes and reproaches. Between wrath and anger (Thumon kai orgen) there is little difference, except that the former denotes the power, and the latter the act; but here, the only difference is, that anger is a more sudden attack. The correction of all the rest will be greatly aided by the removal of malice. By this term he expresses that depravity of mind which is opposed to humanity and justice, and which is usually called malignity.

Let all bitterness - see the notes on Ephesians 4:2.
And wrath - The word here does not differ essentially from anger.
Anger - see the note on Ephesians 4:26. All cherished, unreasonable anger.
And clamour - Noise, disorder, high words; such as men use in a brawl, or when they are excited. Christians are to be calm and serious. Harsh contentions and strifes; hoarse brawls and tumults, are to be unknown among them.
And evil-speaking - Slander, backbiting, angry expressions, tale-bearing, reproaches, etc.
With all malice - Rather, "with all evil" - κακίᾳ kakia. Every kind and sort of evil is to be put away, and you are to manifest only that which is good.

Let all bitterness - Πασα πικρια. It is astonishing that any who profess the Christian name should indulge bitterness of spirit. Those who are censorious, who are unmerciful to the failings of others, who have fixed a certain standard by which they measure all persons in all circumstances, and unchristian every one that does not come up to this standard, these have the bitterness against which the apostle speaks. In the last century there was a compound medicine, made up from a variety of drastic acrid drugs and ardent spirits, which was called Hiera Picra, ἱερα πικρα, the holy bitter; this medicine was administered in a multitude of cases, where it did immense evil, and perhaps in scarcely any case did it do good. It has ever appeared to me to furnish a proper epithet for the disposition mentioned above, the holy bitter; for the religiously censorious act under the pretense of superior sanctity. I have known such persons do much evil in a Christian society, but never knew an instance of their doing any good.
And wrath - Θυμος is more properly anger, which may be considered the commencement of the passion.
Anger - Οργν is more properly wrath - the passion carried to its highest pitch, accompanied with injurious words and outrageous acts, some of which are immediately specified.
And clamor - Κραυγη Loud and obstreperous speaking, brawling, railing, boisterous talk, often the offspring of wrath; all of which are highly unbecoming the meek, loving, quiet, sedate mind of Christ and his followers.
And evil speaking - Βλασφημια· Blasphemy; that is, injurious speaking - words which tend to hurt those of whom or against whom they are spoken.
With all malice - Κακια· All malignity; as anger produces wrath, and wrath clamor, so all together produce malice; that is, settled, sullen, fell wrath, which is always looking out for opportunities to revenge itself by the destruction of the object of its indignation. No state of society can be even tolerable where these prevail; and, if eternity were out of the question, it is of the utmost consequence to have these banished from time.

Let all bitterness,.... These words are a dehortation from several vices good men are liable to, by which the Spirit of God is grieved: "bitterness" sometimes designs the corruption of nature, which is the gall of bitterness, and bond of iniquity; and sometimes actual sins and transgressions, even those of God's own people, which are evil and bitter things; and sometimes heretical doctrines, which are roots of bitterness; and sometimes sinful words spoken by the saints, one against another; and here perhaps it signifies, the first offence taken in the mind, against any person, upon any account, which should at once be put away, and not encouraged:
and wrath: heat of spirit, which follows upon bitterness, or upon the spirit being embittered and offended; see Ezekiel 3:14.
And anger; a sinful one, cautioned against before, Ephesians 4:26.
And clamour and evil speaking; such as brawlings, contentions, contumelies, reproaches, slanders, &c. arising from an embittered, wrathful, and angry disposition: these should all
be put away from you, with all malice; being the deeds of the old man, unbecoming such as are born again, and grieving to the Spirit of God.

bitterness--both of spirit and of speech: opposed to "kind."
wrath--passion for a time: opposed to "tender-hearted." Whence BENGEL translates for "wrath," harshness.
anger--lasting resentment: opposed to "forgiving one another."
clamour--compared by CHRYSOSTOM to a horse carrying anger for its rider: "Bridle the horse, and you dismount its rider." "Bitterness" begets "wrath"; "wrath," "anger"; "anger," "clamor"; and "clamor," the more chronic "evil-speaking," slander, insinuations, and surmises of evil. "Malice" is the secret root of all: "fires fed within, and not appearing to by-standers from without, are the most formidable" [CHRYSOSTOM].

Let all bitterness - The height of settled anger, opposite to kindness, Ephesians 4:32. And wrath - Lasting displeasure toward the ignorant, and them that are out of the way, opposite to tenderheartedness. And anger - The very first risings of disgust at those that injure you, opposite to forgiving one another. And clamour - Or bawling. "I am not angry," says one; "but it is my way to speak so." Then unlearn that way: it is the way to hell. And evil speaking - Be it in ever so mild and soft a tone, or with ever such professions of kindness. Here is a beautiful retrogradation, beginning with the highest, and descending to the lowest, degree of the want of love.
