Usage notes 
The spelling Rebecca originates from the Latin Vulgate, which from the 4th century A.D. was the Bible that was used for centuries in Western Christianity. When the King James Version appeared in 1611, the spelling Rebekah was used in the Old Testament, but the spelling Rebecca was retained in the New Testament.
