εὖ, adverb (properly, εὖ, the unused neuter of the adjective ἐΰς in Homer), well: εὖ πράσσω, not as many interpreters take it, contrary to ordinary Greek usage, to do well i. e. act rightly (which in Greek is expressed by ὀρθῶς or καλῶς πράσσω), but to be well off, fare well, prosper, Acts 15:29 (R. V. it shall be well with you) (Xenophon, mem. 1, 6, 8; 2, 4, 6; 4, 2, 26; oec. 11, 8; Josephus, Antiquities 12, 4, 1; ὅστις καλῶς πραττει, οὐχί καί εὖ πραττει; Plato, Alc. i., p. 116 b.; εἰ εὖ πραττουσι ἀδικουντες, Prot., p. 333 d.; εἰ τίς ἄλλος εὖ μέν ἐποίησεν ὑμᾶς εὖ πράττων, Demosthenes 469, 14; and some began their letters with εὖ πράττειν, cf. 2 Macc. 9:19; (Diogenes Laërtius 3, 61 and Menagius (Menage) in the place cited.

Justin Martyr, Apology 1, 28 and Otto's note; cf. Liddell and Scott, under the word πράσσω, IV.)); ἵνα εὖ σοι γένηται that it may be well, things may turn out well, with thee, Ephesians 6:3 (Genesis 12:13; (Exodus 20:12); Deuteronomy 4:40; (Deuteronomy 4:16); Orat.
