UBS Dictionary of the Greek New Testament
verb | βοάω + θέω
1 The various terms noted in 35.1 (ἀντιλαμβάνω[a], ἐπιλαμβάνομαι[d], ὑπολαμβάνω[c], συμβάλλω[e], παρίστημι[l], ἀντέχω[c], ἐπαρκέω[a], βοηθέω, βοήθεια[a]) with a generic meaning of ‘help’ no doubt possess certain contrastive features of meaning, at least of a connotative type, but there is no specific evidence of this in NT usage.

Moulton & Milligan — Vocabulary of the Greek NT
βοηθέω. Like the noun, the verb is ubiquitous in the formula of petitions, e.g. P Par 2253 (petition of the Serapeum Twins) | ὅπως ὦμεν δι ὑμᾶς βεβοηθημέναι, P Fay 11%! (c. B.c. 115) τούτων δὲ γενομένων ἔσομαι βεβοηθημένίος, P Giss I. 81° (A.D. 110) ἵν᾽ ὦ [β]εβοηθημένος, BGU II. 4545) (A.p. 193) καὶ ὦμεν ὑπό clov βεβοηθημένοι. For its general use cf. P Giss I. 665 (early ii/A.D.) ἃ [ἐϊβεβοηθήκεις αὐτῶι, P Tebt II. 2864 (A.D. 121-38) κ]αὶ πί[ρ]ώην cor ἀπεφηνάμην ὅτι τὸ ἐϊπ]ίκριμά pov βοηθεῖ [o]or. ““ that my edict was of service to you” (Edd.), P. Flor IL. 150° (a.p. 267) πλείονα (sc. βοΐδια) ἕξει βοηθεῖν σε (note case), P Oxy X. 1348 (late iii/A.D.) od yap ἐβοήθησας ἡμῖν ὡς εἰδὼς τὰ [νόϊμιμα. Add from inscrr. Sy// 3291! (B.c. 86), where the Ephesian demos, ἐσχηκὼς καιρὸν πρὸς τὸ βοηθεῖν τοῖς κοινοῖς πράγμασιν, declares war on Mithradates. For divine help cf. Predséghe 158 ᾿Ανδρόμαχος Μακεδὼν ἀφίκετο πρὸς ᾿Αμενώθην χρηστὸν θεὸν μ[ι]σϑοῦ ἐργαζόμενος καὶ ἐμαλακίσϑη καὶ ὁ θεὸς αὐτῶι ἐβοήθησε αὐθημερή, P Leid WY? (ii/ili A.D.) κλῦτι μοι, ὃ χρηστὸς ἐν βαΐζάνοις, βοήθησον ἐν ἀνάγκαις. These prepare for its use in Christian papyri: P Fay 1369 (a letter, iv/A.D.) εἸϊδότες ὅτι ἔχετέ pe is ὅσ᾽ ἄν πάσχετε, θεοῦ βοηθοῦντος, P Oxy VII. 1058* (a prayer, iv/v A.D.) ὁ θ(εδ)ς τῶν παρακειμένων σταυρῶν, βοήθησον τὸν δοῦλόν σου, 2. VIII. 1152* (amulet, v/vi A.D.) Ἰεσοῦ Χριστέ, βοήθι ἡμῖν καὶ τούτῳ οἴκῳ. Inscriptional instances of βοιηθέω are given in G. Meyer Gr.* p. 93: see Brugmann-Thumb G7. p. 54. The verb starts from the military sense, so common in Greek historians: Homeric βοηθόος, from which it comes, ‘* succurrit (θοός) ad clamorem (βοή). ἘΒοηθός was made afresh from the verb.
