“These all died in faith, not having received the promises, but having seen them afar off, and 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 country. And truly if they had been mindful of that country from whence they came out, they might have had opportunity to have returned. But now they desire a better country, that is, an heavenly; wherefore God is not ashamed to be called their God, for He has prepared for them a city.”
