“Be angry, yet do not sin.” Do not let the sun set upon your anger,
26. Be ye angry, and sin not. Whether or not the apostle had in his eye a part of the fourth Psalm is uncertain. The words used by him (᾿Οργίζεσθε καὶ υὴ ἁμαρτάνετε) occur in the Greek translation, though the word ὀργίζεσθε, which is translated, be ye angry, is considered by some to mean tremble. “Stand in awe,” Psalm 4:4.
The apostle having gone through his exhortation to mutual love, unity, and concord, in the foregoing verses, there follows in these an exhortation to Christian purity and holiness of heart and life, and that both more general (Eph 4:17-24) and in several particular instances, Eph 4:25-32.
Commenting on Ephesians 4:17-32
Let no corrupt communication proceed out of your mouth,.... As unsavoury speech, foolish talking, light and frothy language, that which is filthy, unprofitable, noxious, and nauseous, and all that is sinful; such as profane oaths, curses, and imprecations, unchaste words, angry ones, proud, haughty, and arrogant expressions, lies, perjury, &c.
