Definition: "WCU" is a Greek word meaning "a king." It's a verb, but in the context of the Bible, it often refers to the authority or position of a ruler (e.g., King Saul). In Hebrews 1:9-10, it appears as an exclamation about the importance of kingship: "Therefore we do not give heed to those who are evil; for they will be put to death by their own hands. But we have a king over us, and he is in authority."
