What was King Tutankhamun use of gold?
he used gold for his coffin and crown
No. For one thing, Tutankhamun lived several centuries before the time of David. More obviously, Tutankhamun died young (examination of his mummy suggests that he was about 19 years old), whereas David lived a long life. Additionally Tutankhamun was Pharaoh or King in Egypt and David was King in Israel.
