Famous quotes containing the word table:
“When he was at the table with them, he took bread, blessed and broke it, and gave it to them. Then their eyes were opened, and they recognized him; and he vanished from their sight.”
—Bible: New Testament, Luke 24:30,31.
The Emmaus story.
“The best thing about Sassy Seats is that grandmothers cannot figure out how they work and are in constant fear of the childs falling. This often makes them forget to comment on other aspects of the childs development, like why he is not yet talking or is still wearing diapers. Some grandmothers will spend an entire meal peering beneath the table and saying, Is that thing steady? rather than, Have you had a doctor look at that left hand?”
—Anna Quindlen (20th century)
“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.
