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 who is greater, the one who is at the table or the one who serves? Is it not the one at the table? But I am among you as one who serves.”
—Bible: New Testament, Luke 22:27.
