πλοῦτος

πλούτου, ὁ, and (according to L T Tr WH in 2 Cor 8:2; Eph 1:7; Eph 2:7; Eph 3:8, Eph 3:16; Phm 4:19; Col 1:27; Col 2:2, but only in the nominative and accusative; cf. (Tdf. Proleg., p. 118; WHs Appendix, p. 158); Winers Grammar, 65 (64); Buttmann, 22f (20)) τό πλοῦτος (apparently equivalent to πλεοτος, from πλέος full (cf. πίμπλημι)), from Homer down, the Sept. for עֹשֶׁר, and also for הָמון, a multitude, חַיִל, הול; riches, wealth;
a. properly, and absolutely, abundance of external possessions: Mt 13:22; Mk 4:19; Lk 8:14; 1 Tim 6:17; Jas 5:2; Rev 18:17 (16).
b. universally, fullness, abundance, plenitude: with a genitive of the excellence in which one abounds, as τῆς χρηστότητος, Rom 2:4; Rom 9:23; 2 Cor 8:2; Eph 1:7, Eph 1:18; Eph 2:7; Eph 3:16; Col 1:21; Col 2:2. the πλοῦτος of God is extolled, i. e. the fullness of his perfections — of which two are mentioned, viz. σοφία and γνῶσις, Rom 11:33 (for σοφίας καί γνώσεως here depend on βάθος, not on πλούτου (cf. B. 155 (135); Winer's Grammar, § 30, 3 N. 1)); the fullness of all things in store for God's uses, Phm 4:19; in the same sense πλοῦτος is attributed to Christ, exalted at the right hand of God, Rev 5:12; in a more restricted sense, πλοῦτος τοῦ Χριστοῦ is used of the fullness of the things pertaining to salvation with which Christ is able to enrich others, Eph 3:8.
c. universally equivalent to a good ((to point an antithesis)): Heb 11:26; equivalent to that with which one is enriched, with a genitive of the person enriched, used of Christian salvation, Rom 11:12.
