For Palm. see s.vv. brr and bry. The unique Quad t form is probably a scribal error.
LJLA C-stem forms regularly with initial heh, reflecting Biblical Aramaic in both form and meaning. Although manuscripts vary in this corpus, one gets the impression that the core LJLA texts (i.e., targums PsJon, Psalms, and Job) originally used the form with heh as a passive and without as active. Whether or not those authors vocalized the passive forms as הוּבַד as in Dan. 7:11 rather than הוֹבֵד is uncertain.
