Ezekiel 37:18-19

When Ezekiel’s audience asked him what his symbolic act represented (cf. Ezekiel 4:1; Ezekiel 5:1; Ezekiel 12:9; Ezekiel 17:12; Ezekiel 20:49; Ezekiel 24:19), he was to tell them that the Lord said He would combine the two parts of Israel into one whole nation (cf. Isaiah 11:12-13; Jeremiah 3:18; Hosea 1:11). This promise refutes the teaching of British Israelism and other groups who hold that the 10 northern tribes were lost and later became some other national entity (cf. Isaiah 43:5-7; Isaiah 49:5-6; Jeremiah 3:12-15).

"We know comparatively little about the history of the exiled northerners, but there is no evidence of any return. There was Jewish awareness of northern tribes in Assyria: the apocryphal book of Tobit has such a setting." [Note: Allen, Ezekiel 20-48, p. 195.]
