"The voice of the Son of God is heard calling forth the sleeping saints, and as the prophet beholds them coming from the prison house of death, he exclaims, “Thy dead men shall live, together with my dead body shall they arise. Awake and sing, ye that dwell in dust: for thy dew is as the dew of herbs, and the earth shall cast out the dead.” PK 728.1"
