Whereas scholarship generally assumes a fixed text of Jubilees by the
second century B.C.E., this article explores the evidence for first-century B.C.E.
revisions and Fortschreibungen. The combined evidence of 4Q216 and 4Q217
hints at a first-century B.C.E. addition of Jub. 1, and the absence of Jub. 23:32
from 4Q176 frag. 21 may indicate subsequent Fortschreibung. The article
argues, following Milik, for a manuscript bisection of Jubilees, and for a reassignment
of 4Q176 frag. 21 to 4Q221. An appendix presents the hitherto
unpublished fragment 4Q221 frag. 20.
