Luke 11:36

εἰ οὖν τὸ σῶμά σου ὅλον φωτεινόν μὴ ἔχον μέρος τι σκοτεινόν ἔσται φωτεινὸν ὡς ὅταν ὁ λύχνος τῇ ἀστραπῇ φωτίζῃ σε

ei oun to sōma sou holon phōteinon mē echon meros ti skoteinon estai phōteinon hōs hotan ho lychnos tē astrapē phōtizē se

if therefore the body of You whole light not having place anything [is] dark it will be full of light as when - lamp the shining might light You
