Jamieson, Fausset and Brown on Amos 9:7

7. unto me--however great ye seem to yourselves. Do not rely on past privileges, and on My having delivered you from Egypt, as if therefore I never would remove you from Canaan. I make no more account of you than of "the Ethiopian" (compare Jr 13:23). "Have not I (who) brought you out of Egypt," done as much for other peoples? For instance, did I not bring "the Philistines (see on Is 14:29, &c.) from Caphtor (compare De 2:23; see on Jr 47:4), where they had been bond-servants, and the Syrians from Kir?" It is appropriate, that as the Syrians migrated into Syria from Kir (compare Note, see on Is 22:6), so they should be carried back captive into the same land (see on Am 1:15; 2Ki 16:9), just as elsewhere Israel is threatened with a return to Egypt whence they had been delivered. The "Ethiopians," Hebrew, "Cushites," were originally akin to the race that founded Babylon: the cuneiform inscriptions in this confirming independently the Scripture statement (Ge 10:6, 8, 10).
