Hebrews 11:13-15

These all died in faith, not having received the promises, but having seen them afar off, and were persuaded of them, 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.
