κραταιός [page 358]
That this poetic word also formed part of the common stock of the Κοινή is shown by its occurrence not only in the LXX and NT, but in the magic papyri, e.g. P Lond 121 .422 (iii/A.D.) (= I. p. 98) θεοὶ κραταιοί , ib. .563 (= p. 102) ἐν φωτὶ κραταιῷ καὶ ἀφθάρτῳ , ib. .789 (= p. 109) ἐπεύχομαι τῇ δεσποίνῃ τοῦ παντὸς κόσμου , ἐπάκουσόν μου ἡ μόνη (= ι )μος ἡ κρατει (= αι )ά .
