The name of Jacob, the son of Isaac (Genesis 25:26) who was the promised son of Abraham (Genesis 17:19), was changed to Israel when he wrestled with a man of God (Genesis 32:28). Hence, the descendants of Abraham through Isaac and Jacob (Israel) made up the nation of Israel and were sometimes called Israelites (Exodus 9:7). When the nation divided, the ten northern tribes arrogated to themselves the name Israel, and the two southern tribes became known as Judah. Both nations were taken captive; Israel was taken captive by the Assyrians and Judah was later taken captive by the Babylonians. When the Babylonian captivity ended, exiles of both nations- Israel and Judah- returned to their homeland and were again united under the designation of Israel.
