Therefore will I cause you to go into captivity beyond Damascus," says Yahweh, whose name is the God of hosts.
Stephen, in quoting this prophecy, substitutes, Babylon for Damascus, as indeed “the cities of the Medes” were further than Babylon. Perhaps he set the name, in order to remind them, that as God had brought Abraham “out of the land of the Chaldeans” Acts 7:4, leaving the idols which his “fathers” had “served” Joshua 24:14, to serve God only, so they, serving idols, were carried back, from where Abraham had come, forfeiting, with the faith of Abraham, the promises made to Abraham; aliens and outcasts.
