Section 322
99So also in 1 Cor. 6:11, ἀλλὰἀπελούσασθε, ἁαὰλα ἡγɩάσθητε, ἀλλὰ ἐδɩϰαɩώθητε . . . (where ἀπολούω is used in the sense of ϰαθαϱὶζω). In the fourth-century Roman church Tit. 2:14 was quoted in the eucharistic prayer of oblation: “purify for thyself a people of thine own (curiously rendered in Latin populum circumui-talem), zealous for good deeds” (Marius Victorinus, Adversus Arium 1.30; 2.8 [PL 8, 1063B, 1094D]).
100δɩὰ λουτϱοῡ παλɩγγενεσίας. The noun λουτϱόν occurs three times in the LXX: in Cant. 4:2; 6:6, of sheep that have “come up from the washing” (ἀπὸ τοῡ λουτϱοῡ), and in Sir. 34:25, where a man who contracts defilement after washing himself has gained nothing “by his washing” (τῷ λουτϱῷ αὐτοῡ). It is attested as early as Homer, who uses the uncontracted form λοετϱόν, always in the plural (e.g., θεϱμά λοετϱά, “a hot bath,” Iliad 22.444).
101Both imperatives are in the middle voice, βάπτɩσαɩ ϰαὶ ἀπόλουσαɩ, where βάπτɩσαɩ might mean “get yourself baptized” or (as with verbs of washing) “baptize yourself.”
102Gk. ἐπɩϰαλεσὰμενος τò ὄνομα αὐτοῡ, a locution (with Joel 2:32 as a precedent) common in Acts and Paul (Acts 2:21; 9:14, 21; Rom. 10:13; 1 Cor. 1:2).
103Gk. ἐν 
(ἐν being comitative). Another possibility is that the 
was the invocation of the name of Christ by the baptizer on the person being baptized (cf. Acts 15:17 [quoting Amos 9:12]; Jas. 2:7); so H. Schlier, Der Brief an die Epheser, p. 257.
104Gk. ἐπεϱώτημα. For the meaning “pledge” see LSJ; cf. also G. C. Richards, “I Peter iii.21,” JTS 32 (1931), 77; E. G. Selwyn, The First Epistle of St. Peter, pp. 205-06. The meaning “prayer to God for a good conscience” is defended by H. Greeven, TDNT 2, pp. 688-89 (s.v. ἐπεϱώτημα).
