'Old' in the Bible

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

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