πειράω: imperfect middle 3 person (singular and plural), ἐπειρᾶτο, ἐπειρῶντο; perfect passive participle πεπειραμενος (see below); common in Greek writings from Homer down; to try; i. e.: 1. to make a trial, to attempt (A. V. to assay), followed by an infinitive; often so from Homer down; also so in the middle in Act_9:26 R G; (Xenophon, symp. 4, 7; Cyril 1, 4, 5, etc.; often in Polybius; Aelian v. h. I, 34; 2Ma_2:23; 3Ma_1:25; 4Ma_12:2, etc.); hence, πεπειραμενος taught by trial, experienced, Heb_4:15 in certain manuscripts and editions ((Rec.st), Tdf. formerly) (see below, and cf. πειράζω, d. α.). 2. In post-Homer usage with the accusative of a person to test, make trial of one, put him to the proof: his mind, sentiments, temper, Plutarch, Brut. 10; in particular, to attempt to induce one to commit some (especially a carnal) crime; cf. Passow, under the word, 3{a} ; (Liddell and Scott, under the word, A. IV. 2). Hence, πεπειραμενος in Heb_4:15 (see 1 above) is explained by some (cf. Winer's Grammar, § 15. Note at the end) tempted to sin; but the passive in this sense is not found in Greek writings; see Delitzsch at the passage.
