You might want to check that out.
Jesus quoted from the Psalms more than any other book.
That's not what the NT word of God says.
It says it is because God has hardened (blinded) the hearts of a large part of Israel in judgment for rejecting the Christ.
That is NOT POSSIBLE!
After God (Is 53) predicts rejection of Christ by most of the Jewish people; We have
Jer 31:31-34
31 Behold, the days come, saith the Lord, that I will make a new covenant with the house of Israel, and with the house of Judah:
32 Not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt; which my covenant they brake, although I was an husband unto them, saith the Lord:
33 But this shall be the covenant that I will make with the house of Israel; After those days, saith the Lord, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people.
34 And they shall teach no more every man his neighbour, and every man his brother, saying, Know the Lord: for they shall all know me, from the least of them unto the greatest of them, saith the Lord; for I will forgive their iniquity, and I will remember their sin no more.
KJV
and after denouncing Israel for unfaithfulness and threatening punishment in Hos 2:1-13; God says:
Hos 2:14-23
14 Therefore, behold, I will allure her, and bring her into the wilderness, and speak comfortably unto her.
15 And I will give her her vineyards from thence, and the valley of Achor for a door of hope: and she shall sing there, as in the days of her youth, and as in the day when she came up out of the land of Egypt.
16 And it shall be at that day, saith the Lord, that thou shalt call me Ishi; and shalt call me no more Baali.
17 For I will take away the names of Baalim out of her mouth, and they shall no more be remembered by their name.
18 And in that day will I make a covenant for them with the beasts of the field, and with the fowls of heaven, and with the creeping things of the ground: and I will break the bow and the sword and the battle out of the earth, and will make them to lie down safely.
19 And I will betroth thee unto me for ever; yea, I will betroth thee unto me in righteousness, and in judgment, and in lovingkindness, and in mercies.
20 I will even betroth thee unto me in faithfulness: and thou shalt know the Lord.
21 And it shall come to pass in that day, I will hear, saith the Lord, I will hear the heavens, and they shall hear the earth;
22 And the earth shall hear the corn, and the wine, and the oil; and they shall hear Jezreel.
23 And I will sow her unto me in the earth; and I will have mercy upon her that had not obtained mercy; and I will say to them which were not my people, Thou art my people; and they shall say, Thou art my God.
