Isidore of Seville (Etymologiae, VIII, 4) writes:
The Essenes say that is Christ himself who taught them complete abstinence. The Galileans say that Christ come and taught them not to say that Caesar is lord (they should not call Caesar "Lord" ), and not to heed his commands (warmings). The Masbotheans say that it was Christ himself who taught them to sabbatize in everything (to keep the Sabbath in every aspect).
monitus -us, s. m. = counsel, advice, command, admonition, warning
sabbatizare, v. (σαββατίζω) = to sabbatize, to keep the Sabbath, to observe the Sabbath
Masbothei , s. pl. = Masbothei or Masbotheans, Μασβώθεοι
