Definition: Kadbase is a term in the Bible used to describe someone who has not learned or memorized God's Word. It's like saying someone is not understanding His instruction manual, so it can be misunderstood or misinterpreted. The passage in question might be 2 Kings 18:17-20: "And behold, an Egyptian was a stranger in a land which the king did not know; and he was in Egypt for a long time."
