Several times in the New Testament, the KJV, Geneva, and Bishop's Bibles,among other older versions, mention "Sion". Actually, this should be "Zion", the hill near Jerusalem where the Jebusite fortress, conquered by David, stood. According to Deu. 4:48, Sion is Mt. Hermon, also known as Mt. Sirion. Now, why those translators of the past made that booboo, I don't know.
