In Old Testament language, what is anyone who is not a Jew called?
In Old Testament language, anyone not a Jew—not born of Isaac, Jacob, and the twelve sons—is called a Gentile, the Goyim, heathen, or uncircumcised. Psalm 2 uses the specific word heathen. This terminology distinguishes Israel from all other nations.
Les explains that in Old Testament language, and even in the New, anyone who was not a Jew, born of Isaac and Jacob and the twelve sons, is either called a Gentile or the Goyim, or is referred to as heathen or uncircumcised. In the context of Psalm chapter 2, which he calls the outline of the prophetic program, the word used is heathen. So the terms Gentile, Goyim, heathen, and uncircumcised are used for anyone other than Israel.
Psalms 2:1
Why do the heathen rage, and the people imagine a vain thing?
