Bedstead
From BiblePortal Wikipedia
Wilson's Dictionary of Bible Types [1]
Deuteronomy 3:11 (c) This is used as a symbol of the life that Og, King of Bashan, lived. The bedstead was made of iron to make it safe, because he looked after his own safety first. The great size showed that he planned for his own comfort. These two selfish purposes characterize his life and GOD recorded it in the story of the bedstead. Think of reading on his tombstone: "He left a bedstead."
