Isaiah 6:10
10. Make . . . fat— (Ps 119:17). "Render them the more hardened by thy warnings" [MAURER]. This effect is the fruit, not of the truth in itself, but of the corrupt state of their hearts, to which God here judicially gives them over (Isa 63:17). GESENIUS takes the imperatives as futures. "Proclaim truths, the result of which proclamation will be their becoming the more hardened" (Ro 1:28; Eph 4:18); but this does not so well as the former set forth God as designedly giving up sinners to judicial hardening (Ro 11:8; 2Th 2:11). In the first member of the sentence, the order is, the heart, ears, eyes; in the latter, the reverse order, the eyes, ears, heart. It is from the heart that corruption flows into the ears and eyes (Mr 7:21, 22); but through the eyes and ears healing reaches the heart (Ro 10:17), [BENGEL]. (Jer 5:21; Eze 12:2; Zec 7:11; Ac 7:57; 2Ti 4:4). In Mt 13:15, the words are quoted in the indicative, "is waxed gross" (so the Septuagint), not the imperative, "make fat"; God's word as to the future is as certain as if it were already fulfilled. To see with one's eyes will not convince a will that is opposed to the truth (compare Joh 11:45, 46; 12:10, 11). "One must love divine things in order to understand them" [PASCAL].

The veil on Moses' face is further typical of the veil that is on their hearts. untaken away . . . which veil —rather, "the same veil . . . remaineth untaken away [literally, not unveiled], so that they do not see THAT it (not the veil as English Version, but 'THE OLD TESTAMENT,' or covenant of legal ordinances) is done away (2Co 3:7, 11, 13) in Christ" or, as BENGEL, "Because it is done away in Christ," that is, it is not done away save in Christ: the veil therefore remains untaken away from them, because they will not come to Christ, who does away, with the law as a mere letter. If they once saw that the law is done away in Him, the veil would be no longer on their hearts in reading it publicly in their synagogues (so "reading" means, Ac 15:21). I prefer the former.15. the veil is—rather, "a veil lieth upon their heart" (their understanding, affected by the corrupt will, Joh 8:43; 1Co 2:14). The Tallith was worn in the synagogue by every worshipper, and to this veil hanging over the breast there may be an indirect allusion here (see on 1Co 11:4): the apostle making it symbolize the spiritual veil on their heart.
