How many times were the children of God in captivity in the Old Testament?

Answer 1

There are two major periods when the Israelites were in captivity. The first was the captivity in Egypt under Pharaoh and the second was the Babylonian captivity. A third captivity could be considered the Northern Kingdom of Israel being carried off to Assyria - however, this was an apostate group and only children of God by race rather than by religion.
