God said to Abram, “You can know for sure that your descendants will live in a land that is not their own, where they will be slaves, and they will be oppressed for 400 years.
The God of the people of Israel chose our ancestors and made them a strong nation while they lived as foreigners in Egypt. He used his powerful arm to bring them out of Egypt,
God told Abraham that his descendants would be foreigners living in another country and that the people there would make them slaves and mistreat them for 400 years.
Faith led Abraham to live as a foreigner in the country that God had promised him. He lived in tents, as did Isaac and Jacob, who received the same promise from God.
