Hebrews 11:9-10

9Because of his faith, Abraham went to live like a stranger in that foreign country. God had promised to give that country to him, but Abraham lived there in tents. Isaac and Jacob also lived there in tents like strangers. God had also promised them that the land would belong to them one day.

10We see that Abraham was waiting to live in God's special place. That is the city that God himself has built. God has made it very strong so that it will be there for ever.
