Additional Note §27
§27 Repeated Call to Rejoice (Phil. 4:4)
Paul repeats and emphasizes the exhortation of 3:1.
4:4 / The adverb always makes it plain that this is no mere formula of farewell; the verb rejoice has its full sense. Compare 1 Thessalonians 5:16, “be joyful always.” Here clearly the Lord is to be the object of their joy.
I will say it again: the verb is unambiguously in the future tense (erō). “I have said it once,” Paul means, “and I will say it a second time” (for emphasis).
4:4 / In The NT: An American Translation this verse is rendered “Good-bye, and the Lord be with you always. Again I say, good-bye.” Cf. its rendering of 3:1, with E. J. Goodspeed, Problems of NT Translation, pp. 174, 175.
