Definition: The word 'isaiah' comes from Hebrew (ΧΦ·ΧͺΦ΅ΦΌΧ) and means "holy" or "wicked," hence being a "worshiper." In the Bible, it has been used as a name for many people in various ways. The most famous use of this word is by Jesus Christ, who became known to the Hebrews as "Isaiah" (Is 7:1). He is often described as the prophet sent by God to warn Israel against false prophets and to deliver them from the bondage of slavery.
