Famous quotes containing the word table:
“When you got to the table you couldn’t go right to eating, but you had to wait for the widow to tuck down her head and grumble a little over the victuals, though there warn’t really anything the matter with them. That is, nothing only everything was cooked by itself. In a barrel of odds and ends it is different; things get mixed up, and the juice kind of swaps around, and the things go better.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“Thou preparest a table before me in the presence of mine enemies; thou anointest my head with oil; my cup runneth over.”
—Bible: Hebrew Psalms, 23:5.
“Remember thee?
Ay, thou poor ghost, whiles memory holds a seat
In this distracted globe. Remember thee?
Yea, from the table of my memory
I’ll wipe away all trivial fond records,
All saws of books, all forms, all pressures past
That youth and observation copied there,
And thy commandment all alone shall live
Within the book and volume of my brain,”
—William Shakespeare (1564–1616)
