1. to bring to, bring near; thus very frequent in Greek writings from Herodotus down with ναῦν (quite as often omitting the ναῦν) and a dative of place, or followed by πρός with an accusative of place, to bring a ship to land, and simply to touch at, put in.

Buttmann, 337 (290); Winers Grammar, 567 (518); yet see ἐπί, B. 2 f. α.); with the addition of ἀπό τίνος, to be on one's guard against, beware of, a thing (cf. Buttmann, § 147, 3 (ἀπό, I. 3 b.)): Luke 12:1 (Tobit 4:12; (Test xii. Patr., test. Dan 6)); also without the dative προσέχειν ἀπό τίνος: Matthew 7:15; Matthew 10:17; Matthew 16:6, 11; Luke 20:46, (Sir. 6:13 Sir. 11:33 Sir. 17:14 Sir. 18:27; ('Teaching' etc. 6, 3 [ET]; 12, 5 [ET])); followed by μή with an infinitive, to take heed lest one do a thing, Matthew 6:1; ἐμαυτῷ, μήποτε with the subjunctive Luke 21:34; absolutely to give attention, take heed: Sir. 13:13; the Epistle of Barnabas 4, 9 [ET]; 7, 4 [ET], 6.
