JMNT(i)
12 "to the end that, 'continuously looking (observing), they may continually look (observe) and yet can (may; should; would) not see so as to perceive, and constantly (or: repeatedly) hearing, they may continually hear, and yet can (may; should; would) not make things flow together so as to comprehend or understand, nor can they at some point turn about (or: unless they turn upon [their path]) and the results (effects) of [their] sins and mistakes should be sent away (set aside; divorced; forgiven) for (or: in) them.'" [Isa. 6:9-10; note: this reading follows synagogue paraphrase, as witnessed in the Peshitta and the Targum, while differing from the Hebrew and LXX – J. Jeremias]
