The answer is: Og

Deut 3:11 - Goliath undoubtedly had a big bed too, but we're not told how big.

In the land of the ancient Near East, where the Bible stories unfold, Og, King of Bashan, takes quite a mighty place in our discussions. He was no ordinary giant; his bed alone was a testament to his stature, measuring an impressive 13.5 feet long by 6 feet wide according to Deuteronomy 3:11! That's some serious real estate for a bed—almost the size of a small room! Imagine the construction of that giant-sized mattress!

That Og's oversized bed gives us a peek into a culture filled with stories of people who were larger than life, not unlike Goliath later on. While we don’t know the measurements of Goliath's bed, he was described as a formidable figure at nearly 9 feet tall (1 Samuel 17:4), also shrouded in mystery and myth; there's an interesting connection in their portrayal as symbols of the supposedly "uncertain and chaotic" forces that the Israelites faced.

Og is often depicted as a remnant of the giants – descendants from the Nephilim, as per Genesis 6, connecting these protagonists to an echo of powerful beings. The mention of giants might spark awe, dread, or intrigue among the people, symbolizing challenges to be overcome. Interestingly, despite their sheer size, both Og and Goliath ultimately serve a narrative purpose encouraging faith and resilience. The tales of giants convey grand themes of courage against overwhelming odds that still resonate powerfully today.
