Famous quotes containing the word verified:
“Don Pedro. Officers, what offence have these men done?
Dogberry. Marry, sir, they have committed false report; moreover they have spoken untruths; secondarily, they are slanders; sixth and lastly, they have belied a lady; thirdly, they have verified unjust things; and, to conclude, they are lying knaves.”
—William Shakespeare (1564–1616)
