Goyim Are Here to Serve the Jews
All three of the terms- Hebrews, Israelltes and Jews-continued to be used in the New Testament to describe the fleshly descendants of Abraham through Isaac and Jacob (2 Corinthians 11:22; John 4:9). Furthermore, since the Israelites were God's chosen people of the Old Testament, in the New Testament the terms Jew and Israel are occasionally used figuratively to represent God's chosen people today- the spiritual seed of Abraham, the church (Galatians 3:29; Romans 2:27,28; 9:6). A careful study of the context of New Testament passages will allow one to discern which way the terms are used in the New Testament and of whom they speak. There are only a few times in the New Testament that a special meaning is given to the words.
