βαπτισμός — baptismós
βαπτισμός, βαπτισμου, ὁ (βαπτίζω), a washing, purification effected by means of water: Mar 7:4; Mar 7:8 (R G L Tr in brackets) (ξεστῶν καί ποτηρίων); of the washings prescribed by the Mosaic law, Heb 9:10. βαπτισμῶν διδαχῆς equivalent to διδαχῆς περί βαπτισμῶν, Heb 6:2 (where L text, WH text, βαπτισμῶν διδαχῆς), which seems to mean an exposition of the difference between the washings prescribed by the Mosaic law and Christian baptism. (Among secular writings Josephus alone, Antiquities 18, 5, 2, uses the word, and of John's baptism; (respecting its interchange with βάπτισμα cf. examples in Sophocles Lexicon, under the word 2 and Lightfoot on Col 2:12, where L marginal reading Tr read βαπτισμός; cf. Trench, § xcix.).)
