'Old' in the Bible

Turn again, my daughters, go your way; for I am too old to have an husband. If I should say, I have hope, if I should have an husband also to night, and should also bear sons;

surely you would not want to wait until they were old enough to marry! Surely you would not remain unmarried all that time! No, my daughters, you must not return with me. For my intense suffering is too much for you to bear. For the Lord is afflicting me!"

And he shall be unto thee a restorer of thy life, and a nourisher of thine old age: for thy daughter in law, which loveth thee, which is better to thee than seven sons, hath born him.
