to seek a definite thing: to go after some particular person, thing, or answer that one wants, has lost, or has a claim to
This is the everyday Greek verb for seeking, ζητέω, with a prefix attached. Older commentaries and popular word studies took that prefix to turn up the heat, so the word was glossed "seek diligently" or "crave." Most scholars now read it differently: the prefix points rather than intensifies. The seeking has a definite target in view, and otherwise the word sits very close to the plain verb for seeking.
Because the target can be almost anything, one word covers a wide spread of situations:
- looking for a person who has slipped away or is wanted by the authorities
- wanting something badly enough to chase after it
- reaching for a homeland and a city not yet arrived at
- pressing a demand for proof
- asking that a matter be taken up and settled in the proper assembly
Everyday paperwork from Roman Egypt shows officials using this verb for requiring a document, wanting a criminal, or calling for a ship to be unloaded, so it is at home in the language of business and law. The ancient Greek translation of the Old Testament also used it for seeking the Lord and inquiring of him through a prophet, and that older echo stands behind the letter to the Hebrews, where the faithful are people who keep seeking a city still to come.
Where a verse feels urgent, the urgency usually comes from the scene rather than from the word. The crowds hunting Jesus down are pictured as keeping at it, the nations chasing food and clothing are surrounded by anxious talk, and Paul in Romans pairs this verb with a matching one for hitting the mark, so that Israel seeks and yet does not land on what it sought.
Nuances
Whether Matthew's compound ἐπιζητεῖ in the sign demand carries a sharpened sense of insistent demand, given that the Markan parallel (Mark 8:12) has the simplex ζητεῖ.
- majorityThe substitution is a deliberate Matthean strengthening: the generation demands, insists on a sign, which suits the polemical framing of an evil and adulterous generation.; W. D. Davies and D. C. Allison, Matthew, ICC, vol. 2 (1991), on Matt 12:39; D. A. Hagner, Matthew 1-13, WBC 33A (1993), on Matt 12:39; J. Nolland, The Gospel of Matthew, NIGTC (2005), on Matt 12:39; BDAG, s.v. ἐπιζητέω, sense 2
- minorityThe substitution reflects Matthean style rather than a semantic upgrade, so the verb means no more than "seek."; U. Luz, Matthew 8-20, Hermeneia (2001), on Matt 12:39
