Famous quotes containing the word table:

    “But hospitality must be for service, and not for show, or it pulls down the host. The brave soul rates itself too high to value itself by the splendor of its table and draperies. It gives what it hath, and all it hath, but its own majesty can lend a better grace to bannocks and fair water than belong to city feasts.”
    —Ralph Waldo Emerson (1803–1882)

    “For the elemental creatures go
    About my table to and fro,
    That hurry from unmeasured mind
    To rant and rage in flood and wind....
    ”
    —William Butler Yeats (1865–1939)

    “In this sad state, God Tender Bowells run
    Out streams of Grace: And he to end all strife
    The Purest Wheate in Heaven, his deare-dear Son
    Grinds, and kneads up into this Bread of Life.
    Which Bread of Life from Heaven down came and stands
    Disht on thy Table up by Angells Hands.”
    —Edward Taylor (1645–1729)
