Proverbs 25:3

The heaven for height— "It is almost as impossible for the generality of minds to penetrate into the secrets of state, and understand the counsels and designs of intelligent princes, and the various ways and means whereby they consult to effect their ends, as it is to know how far it is from hence to the highest heavens; or how far to the centre of the earth upon which we tread." See Lord Bacon's Advanc. of Learn. book 8: chap. 2.
