Are Jews descendants of Abraham? No, they are not. This is admitted by the Jewish Rabbis themselves and the Jewish encyclopedia.
Abraham's descendants have always been referred to as Israelites.
Jew was a word used when the serpent seed race who infiltrated the temple and Judea before the time of Jesus Christ's birth. Jesus in the book of Acts tells you who they are.
Israelites come from the seventh son of Adam. Adam means to blush or have the blood seen through the skin /white/.
If you are mongrelized you are no longer Adamic or an Israelite. This is God's divine law "do not commit adultery". Adultery is a Greek word meaning do not mix.
Jews are a mongrelized serpent seed race. The KJV of the scripture explains all of this.
Jew in Hebrew is Yuhedin meaning accursed.
This is language and history. Are all Jews bad? The God of Abraham, Isaac and Jacob said they were. The serpent seed race makes war on HIS children.
