The God of the people of Israel chose our ancestors and made the people a great nation during the time they lived as foreigners in Egypt. God brought them out of Egypt by his great power,

By faith he lived 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.

The LORD said to Abram, "Leave your country, your relatives, and your father's home, and go to a land that I am going to show you.

I will bless those who bless you, But I will curse those who curse you. And through you I will bless all the nations."

The LORD said to him, "Your descendants will be strangers in a foreign land; they will be slaves there and will be treated cruelly for four hundred years.

This is what God said to him: 'Your descendants will live in a foreign country, where they will be slaves and will be badly treated for four hundred years.

Now, God made his promises to Abraham and to his descendant. The scripture does not use the plural "descendants," meaning many people, but the singular "descendant," meaning one person only, namely, Christ.

What I mean is that God made a covenant with Abraham and promised to keep it. The Law, which was given four hundred and thirty years later, cannot break that covenant and cancel God's promise.
