Amos 9:4

The Lord would even slay the Israelites whom their enemy led away into captivity. Yahweh would order the sword to slay them even there, though there they would be under the protection of a strong foreign power. They would not be able to hide from His all-seeing eye. Normally God watched over His people for their good, but here He promised to set His eyes on them for evil. His purpose and intention for them was evil from their viewpoint. So thorough was the dispersion following the Assyrian invasion of Israel that the exiles came to be known as the "lost tribes." They were not really lost, however, as later revelation makes clear (Amos 9:11-15; et al.).
