There is all of mankind, Hebrews, Israel, and Judah (Jews). They are subsets. So many people don't understand that real Jews are a small percentage of the Israelites.

Israel in the Bible was a people. Israel today is a country in the middle east that may or may not contain some Israelites and some Jews. But most of the people in the country of Israel are not of Semitic ancestry, as proved by random DNA tests.

So Israel in the Bible is not connected to the people who call themselves Jews. The Bible referred to them as the "synagogue of Satan."

Ashkenazi Jews are supposedly descended from Ashkenaz, a descendant of Japheth (the white Europeans eventually), although I've read somewhere that they were really descended from Togarmah, a brother of Ashkenaz. I haven't been down that rabbit hole yet.
