ἐνθυμέομαι [page 214]
For this verb, which is common in the LXX, but in the NT is confined to Mat_1:20 ; Mat_9:4 , see PSI IV. 436 .9 (B.C. 248 7) ἐνθυμηθεὶς ἵνα μηθείς [με ] . . . ἀδικῆι , P Tebt I. 27 .77 (B.C. 113) καθόλου δ᾽ ἐνθυμηθεὶς ἡλίκην συμβάλλεται ἡ περὶ τὰ ὑποδεικνύμεν [α ] προσοχὴι τοῖς πράγμασι ῥοπήν , in general consider how great an impulse attention to the matters indicated contributes to business, P Oxy XII. 1477 .13 (iii/iv A.D.) εἶ δύναμαι ὃ ἐ̣νθυμοῦμαι ἆρ̣α̣[ι ; Am I able to carry off what I am thinking of? (Edd.). For the gen. constr. see P Lond 42 .20 (B.C. 168) (= I. p. 30, Selections, p. 10), σὲ δὲ μηδ᾽ ἐντεθυμῆσθαι τοῦ παραγενέσθαι , and that you have never even thought of returning, P Par 63 .201 (B.C. 164) φαίνεσθε οὖν μηδὲ κατὰ μικρὸν ἐντεθυμῆσθαι τῶν ἐξηριθμημένων ὑμῖν , you appear therefore not to have understood in the smallest degree the points enumerated to you (Mahaffy). The late compd. παρενθυμέομαι disregard, neglect, occurs in a Lycian inscr., JHS xxxiv. p. 5, No. 10 .13 ἐὰν δέ τις παρενθυμηθεὶς μὴ θύσῃ , ἔσται αὐτῷ ἐπιβλαβῆ . MGr θυμοῦμαι (c. acc.), remember, a meaning which gives good sense in Wis_7:15 , if with ΰ A we read ἐνθυμηθῆναι ἀξίως τῶν λεγομένων (cf. Goodrick Oxf. Ch. Bibl. Comm. ad l. ).
