Apostol § 328

Brethren, by faith Abraham sojourned in the land of promise as in a strange country, dwelling in tents with Isaac and Jacob, the heirs with him of the same promise; for he looked for the city which has foundations, whose builder and maker is God... By faith Sarah herself also received strength to conceive seed, and she bore a child when she was past the age, because she judged Him faithful who had promised. Therefore from one man, and him as good as dead, were bom as many as the stars of the sky in multitude, innumerable as the sand which is by the sea. These all died in faith, not having received the promises, but having seen them afar off, were assured of them, embraced them, and confessed that they were strangers and pilgrims on the earth. For they that say such things declare plainly that they seek a homeland. And tmly, if they had called to mind that country from which they had come out, they would have had opportunity to return. But now they desire a better, that is, a heavenly country. Therefore God is not ashamed to be called their God, for He has prepared a city for them...
