Deut. 33:17 "His glory is like the firstling of his bullock, and his horns are like the horns of unicorns: with them he shall push the people together to the ends of the earth: and they are the ten thousands of Ephraim, and they are the thousands of Manasseh." Is the KJV's rendering "unicorns" the historically attested rendering of the pre-1611 English Bibles? Is the KJV's rendering "unicorns" at this verse the most accurate rendering of the Hebrew word used in this verse? Was the Hebrew word translated "unicorns" singular or plural in number? Does the context support the KJV's rendering in this verse? To what animal does the KJV's rendering "unicorns" refer?
