James 5:19

πλανηθῇ : “The passive aorist is used with a middle force in classical writers, as well as in the LXX, Deuteronomy 32:1; Psalms 119:176; Ezekiel 34:4 ” (Mayor). ἀπὸ τῆς ἀληθείας : Cf. Mark 12:14, … ἐπʼ ἀληθείας τὴν ὁδὸν τοῦ θεοῦ διδάσκεις, this seems to be the way in which ἀληθεία is here used, cf. John 3:21; John 5:33; John 8:32. ἐπιστρέψῃ : excepting here (and in the next verse) and Luke 1:16-17 this word is always used intransitively in the N.T. (cf. however Acts 26:18).
