JMNT(i)
14 But further, the results of their mental conceptions, intellectual workings and thought processes were petrified (made to be a stony concretion; were hardened and made callous [note: the word became a medical term for being covered with thick skin]),
for until this very day the same head-covering (veil)
continues remaining (dwelling; abiding)
upon the reading of the old covenant (arrangement; thorough placement) –
it [i.e., the reading of the old, or the old covenant itself]
continues not being uncovered or unveiled – because it [i.e., the old covenant and arrangement]
continues being progressively and fully unemployed and brought down to doing no work and being made useless, ineffective and nullified within Christ (or: = the old arrangement and covenant is nullified in union with [the] Anointing, and in the midst of Christ).
15 Still furthermore, until today, whenever Moses should be repeatedly read [e.g., in the synagogue],
a head-covering (veil)
continues lying upon their heart (= the innermost being of the group).
