Question: where in the bible does it talk about the 10 lost tribes?
Answer: The scriptural basis for the idea of "10 Lost Tribes" is 2 Kings 17:6: "In the ninth year of Hoshea, the king of Assyria captured Samaria and deported the Israelites to Assyria. He settled them in Halah, in Gozan on the Habor River and in the towns of the Medes."
