Sebuans
From BiblePortal Wikipedia
Sebuans [1]
the name given to the second of the four Samaritan sects named by Epiphanius, the other three being the Essenes, Gorttaeans, and Dositheans. It was originated by Sebua, or Sebuiah; and, partly to suit their own convenience, and partly through hostility to the Jews, kept the sacred festivals at different periods from them viz. the Passover and Pentecost in autumn, and the Feast of Tabernacles in the time usually allotted for the Passover. This sect was not permitted to worship along with the other Samaritans in the temple on Mount Gerizim. Lightfoot, in his Horae Talmudicae considers them to be identical with the Sabaeans.
