to set about doing something: to take a task in hand and try to carry it out
The word pictures someone putting a hand to a job and setting to work at it. At its core it simply means to take up a task and try to do it, and by itself it says nothing about whether the effort is good or bad, whether it succeeds or fails. That verdict comes entirely from the surrounding story.
In practice, though, the word tends to show up around bold, presumptuous, or doomed ventures. In the Greek Old Testament it is used again and again of enemies moving against God's people, and in everyday Greek documents it often introduces the wrongdoing a complaint is protesting. Both of its appearances in Acts describe attempts that collapse: men who keep trying to kill Paul, and would-be exorcists who end up beaten and humiliated. So while the plain sense is neutral, readers who knew their Greek Bible would have heard an undertone of a rash or ill-fated undertaking.
That undertone is exactly what makes the word interesting in Luke's opening line, where he says many have taken it in hand to write an account of Jesus. Read flatly, he is just noting that others have done the work he is now doing. But because he could have chosen a plainer word, some readers hear a gentle hint that those earlier accounts, while worthy, fell short of the careful, orderly record he means to provide.
Whether Luke's use of ἐπιχειρέω in the preface (Luke 1:1) carries an implied criticism of his predecessors' accounts or is a neutral term for taking up a task.
- majorityNeutral: the verb is stock preface diction implying no censure, since Luke aligns himself with the same predecessors in the next clause (kagō, "it seemed good to me also") and honors the tradition they drew on.; H. J. Cadbury, "Commentary on the Preface of Luke," in The Beginnings of Christianity, Part I, vol. 2 (1922); Joseph A. Fitzmyer, The Gospel According to Luke I-IX, Anchor Bible (1981); I. Howard Marshall, The Gospel of Luke, NIGTC (1978)
- minorityMildly critical: read against Greek scientific and historiographical prefaces, the third-person use of the verb of predecessors carries a gentle deflation, so Luke acknowledges earlier accounts while presenting his own careful, orderly record as the more secure alternative.; Loveday C.
