Hebrews 11:8-10 New Revised Standard Version (NRSV)
The Faith of Abraham
8 By faith Abraham obeyed when he was called to set out for a place that he was to receive as an inheritance; and he set out, not knowing where he was going. 9 By faith he stayed for a time in the land he had been promised, as in a foreign land, living in tents, as did Isaac and Jacob, who were heirs with him of the same promise. 10 For he looked forward to the city that has foundations, whose architect and builder is God.
