That is correct, although some later sources give it as Iesus Nazarenus Rex Iduaerum. See, the original Latin alphabet had neither the letter 'J' nor the letter 'V' but as time went on, medieval monks, rendering the original into Church Latin, changed some spellings to conform to more "modern" typography.
