Famous quotes containing the words time and/or served:
“Out-worn heart, in a time out-worn,
Come clear of the nets of wrong and right;
Laugh, heart, again in the grey twilight,
Sigh, heart, again in the dew of the morn.”
—William Butler Yeats (1865–1939)
“It will not be so among you; but whoever wishes to be great among you must be your servant, and whoever wishes to be first among you must be your slave; just as the Son of Man came not to be served but to serve, and to give his life a ransom for many.”
—Bible: New Testament, Matthew 20:26-28.
