John Gills Exposition of the Bible Commentary

Verse 31 (Ephesians 4:31)

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.
