QUESTION:
Do any Jewish people today know which tribes they come from?”
ANSWER:
No when the Temple at Jerusalem was destroyed in A.D. 70, the tribal records were also destroyed. Therefore, none of the Jewish people of today know for certain from which tribes they are descended. Yet, we can be assured that God knows, and when the time comes for God to seal the 144,000, He will reveal the identity of all the tribes (Rev. 7:2-8).
Revelation 7:2-8 (NASB) 2And I saw another angel ascending from the rising of the sun, having the seal of the living God; and he cried out with a loud voice to the four angels to whom it was granted to harm the earth and the sea, 3saying, “Do not harm the earth or the sea or the trees until we have sealed the bond-servants of our God on their foreheads.” 4And I heard the number of those who were sealed, one hundred and forty-four thousand sealed from every tribe of the sons of Israel: 5from the tribe of Judah, twelve thousand were sealed, from the tribe of Reuben twelve thousand, from the tribe of Gad twelve thousand, 6from the tribe of Asher twelve thousand, from the tribe of Naphtali twelve thousand, from the tribe of Manasseh twelve thousand, 7from the tribe of Simeon twelve thousand, from the tribe of Levi twelve thousand, from the tribe of Issachar twelve thousand, 8from the tribe of Zebulun twelve thousand, from the tribe of Joseph twelve thousand, from the tribe of Benjamin, twelve thousand were sealed.
