2. a deacon, one who, by virtue of the office assigned him by the church, cares for the poor and has charge of and distributes the money collected for their use (cf. BB. DD., Dict. of Christ. Antiq., Schaff-Herzog under the word ; Lightfoot's Commentary on Philippians, dissert. i. § i.; Julius Muller, Dogmatische Abhandlungen, p. 560ff): Philippians 1:1; 1 Timothy 3:8, 12, cf. Acts 6:3ff; ἡ διάκονος, a deaconess (ministra, Pliny, epistles 10, 97), a woman to whom the care of either poor or sick women was entrusted, Romans 16:1 (cf. Dictionaries as above, under the word ; Lightfoot as above, p. 191; B. D. under the word ).

3. a waiter, one who serves food and drink: John 2:5, 9, as in Xenophon, mem. 1, 5, 2; Hier. 3, 11 (4, 2); Polybius 31, 4, 5; Lucian, de merced. cond. § 26; Athen. 7, p. 291 a.; 10, 420 e.; see διακονέω, 2 and διακονία, 5; (also Wetstein (1752) on Matthew 4:11). [SYNONYMS: διάκονος, δοῦλος, θεράπων, ὑπηρέτης: "διάκονος represents the servant in his activity for the work; not in his relation, either servile, as that of the δοῦλος, or more voluntary, as in the case of the θεράπων, to a person" Trench; yet cf. e. g. Romans 13:4; 2 Corinthians 6:4 etc.). δοῦλος opposed to ἐλεύθερος, and correlate to δεσπότης or κύριος, denotes a bondman, one who sustains a permanent servile relation to another. θεράπων is the voluntary performer of services, whether as a freeman or a slave; it is a nobler, tenderer word than δοῦλος. ὑπηρέτης according to its etymol. suggests subordination. Cf. Trench, § ix.; B. D. under the word ; Meyer on Ephesians 3:7; Schmidt, chapter 164.]
