How do you interpret this scripture?
This is in respect to the difference between the Old Testament (Moses and the Law/Torah) and the apostolic gospel
of the New Testament. The veil (blindness, not seeing the truth, not having full understanding) prevents OT Jews from
embracing with joy Jesus as their Messiah and in receiving the gift of the Holy Spirit [the Book of Acts].
7 What then? Israel hath not obtained that which he seeks for; but the election has obtained it, and the rest were blinded
8 (According as it is written, God hath given them the spirit of slumber, eyes that they should not see,
and ears that they should not hear) unto this day.
9 And David saith, Let their table be made a snare, and a trap, and a stumbling block, and a recompence unto them:
10 Let their eyes be darkened, that they may not see, and bow down their back alway.
Romans 11:7-10
25 For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits;
that blindness in part is happened to Israel, until the fulness of the Gentiles be come in.
26 And so all Israel shall be saved: as it is written, There shall come out of Zion the Deliverer, and shall turn away ungodliness from Jacob:
27 For this is my covenant unto them, when I shall take away their sins.
28 As concerning the gospel, they are enemies for your sakes: but as touching the election, they are beloved for the fathers' sake.
Romans 11:25-28
