Comparative of presbus (elderly); older; as noun, a senior; specially, an Israelite Sanhedrist (also figuratively, member of the celestial council) or Christian "presbyter" -- elder(-est), old.
1. of age;
a. where two persons are spoken of, the elder: ὁ υἱός ὁ πρεσβύτερος (Aelian v. h. 9, 42), Luke 15:25.
b. universally, advanced in life, an elder, a senior: opposed to νεανίσκοι, Acts 2:17; opposed to νεώτερος, 1 Timothy 5:1f (Genesis 18:11f; Wis. 8:10; Sir. 6:34 (33); 2. a term of rank or office; as such borne by, a. among the Jews, α. members of the great council or Sanhedrin (because in early times the rulers of the people, judges, etc., were selected from the elderly men): Matthew 16:21; Matthew 26:47, 57, 59 Rec.; b. among Christians, those who presided over the assemblies (or churches): Acts 11:30; Acts 14:23; Acts 15:2, 4, 6, 22; Acts 16:4; Acts 21:18; 1 Timothy 5:17, 19; Titus 1:5; 2 John 1:1; 3 John 1:1; 1 Peter 5:1, 5; with τῆς ἐκκλησίας added, Acts 20:17; James 5:14. That they did not differ at all from the (ἐπίσκοποι) bishops or overseers (as is acknowledged also by Jerome on Titus 1:5 (cf. Lightfoot's Commentary on Philippians, pp. 98f, 229f)) is evident from the fact that the two words are used indiscriminately, Acts 20:17, 28; Titus 1:5, 7, and that the duty of presbyters is described by the terms ἐπισκοπεῖν, 1 Peter 5:1f, and ἐπισκοπή, Clement of Rome, 1 Cor. 44, 1 [ET]; accordingly only two ecclesiastical officers, οἱ ἐπίσκοποι and οἱ διάκονοι, are distinguished in Philippians 1:1; 1 Timothy 3:1, 8. The title ἐπίσκοπος denotes the function, πρεσβύτερος the dignity; the former was borrowed from Greek institutions, the latter from the Jewish; cf.
