'Gentiles' in the Bible

It is reported commonly that there is fornication among you, and such fornication as is not so much as named among the Gentiles, that one should have his father's wife.

But I say, that the things which the Gentiles sacrifice, they sacrifice to devils, and not to God: and I would not that ye should have fellowship with devils.

Give none offence, neither to the Jews, nor to the Gentiles, nor to the church of God:

Ye know that ye were Gentiles, carried away unto these dumb idols, even as ye were led.

For by one Spirit are we all baptized into one body, whether we be Jews or Gentiles, whether we be bond or free; and have been all made to drink into one Spirit.
