"The Bab was subjected to a closer and more rigorous confinement at Chihriq than he had been at Mah-Ku. Hence he used to call the former `the Grievous Mountain' (Jabal-i-Shadid the numerical value of the word `Shadid'--318--being the same as that of the name Chihriq), and the latter `the Open Mountain' (Jabal-i-Basit)."
