G1482–ἐθνικός–ethnikos

And if ye salute your brethren only, what do ye more than others? do not even the publicans so?

ἐθνικοὶ ethnikoi “Gentiles”

But when ye pray, use not vain repetitions, as the heathen do: for they think that they shall be heard for their much speaking.

ἐθνικοί· ethnikoi “pagans;”

And if he shall neglect to hear them, tell it to the church: but if he shall neglect to hear the church, let him be to thee as a heathen and a publican.

ἐθνικὸς ethnikos “pagan”

Because for his name's sake they went forth, taking nothing from the Gentiles.

ἐθνικῶν. ethnikōn “Gentile [people].”
