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 unto the church: but if he neglect to hear the church, let him be unto thee as an heathen man and a publican.

ἐθνικὸς ethnikos “pagan”

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

ἐθνικῶν. ethnikōn “Gentile [people].”
