do you have a date for that expulsion from Khazaria? the story i’m familiar with is that after ancient Israel split from Judah (somewhere around 900BC), the northern kingdom was exiled by the Assyrians in the 700s never to return again to Caanan, and then the southern kingdom was taken captive by the Babylonians later (i think around 500BC). the Judahites were allowed to return and rebuild Jerusalem 70 years later (Daniel and Nehemiah both talk about this). i’m wondering if the Khazarians were expelled somewhere around that time then either migrated to Caanan and mixed with the Judahites, or migrated to Babylon and some of them mixed with the Judahites and then went to Caanan with them when they began to rebuild Jerusalem.
