Be of the same mind one toward another. Mind not high things, but condescend to men of low estate. Be not wise in your own conceits.
Be of the same mind one toward another - literally, 'Being of the same mind.' But this is not to be understood merely as part of the preceding sentence: it is merely a resumption of the participial construction of most of these exhortations (as Romans 12:12-13), and is to be regarded as a distinct and independent counsel to cherish and manifest a lively feeling of the common bond which binds all Christians to each other, whatever diversity of station, cultivation, temperament, or gifts may obtain among them. This is finely enlarged on in the two following clauses:
Mind ('Minding') not high things - Cherish not ambitious or aspiring purposes and desires, which, as they spring from selfish severance of our own interests and objects from these of our brethren, are quite incompatible with the spirit inculcated in the preceding clause:
But condescend ('condescending') to men of low estate, х tois (G3588) tapeinois (G5011) sunapagomenoi (G4879)]. As the noun here may be either masculine or neuter, some critics prefer the neuter, thinking it forms a more natural contrast to the preceding clause, thus: 'Minding not high things, but inclining unto the things that be lowly' (so Calvin, Fritzsche, DeWette, Meyer, and Philippi). But the verb-which signifies to 'be drawn away along with,' and is used sometimes in a bad sense (as Galatians 2:13 and 2 Peter 3:17) - agrees best with the masculine sense of our own version. (In this sense it is taken here generally by the Greek fathers, and by Erasmus, Beza, Grotius, Estius, Bengel, Tholuck, Alford).
Be not wise in your own conceits. This is just the application of the caution against high-mindedness to the estimate we form of our own mental character.
