Slightly off-topic: Why do people always refer to the 10 lost tribes, when there should only be 9 lost tribes?
When the Rechavam’s kingdom was split, he kept Yehuda, Benyamin and Shimon (which was within Yehuda). Yerovam took Rueven, Yisaschar, Zevulun, Dan, Naftali, Gad, Ashar, Menashe, and Ephraim.
Levi was split across both Kingdoms.
