'Enlargement' in the Bible

To the Overseer with Stringed Instruments. -- A Psalm of David. In my calling answer Thou me, O God of my righteousness. In adversity Thou gavest enlargement to me; Favour me, and hear my prayer.

Days of our years, in them are seventy years, And if, by reason of might, eighty years, Yet is their enlargement labour and vanity, For it hath been cut off hastily, and we fly away.
