Romans 2:5

For God shall bring every work into judgment, with every secret thing, whether it be good, or whether it be evil.

For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who hold the truth in unrighteousness;

While it is said, To day if ye will hear his voice, harden not your hearts, as in the provocation.

But the heavens and the earth, which are now, by the same word are kept in store, reserved unto fire against the day of judgment and perdition of ungodly men.

And the angels which kept not their first estate, but left their own habitation, he hath reserved in everlasting chains under darkness unto the judgment of the great day.

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.

For the great day of his wrath is come; and who shall be able to stand?

Riches profit not in the day of wrath: but righteousness delivereth from death.

For it was of the LORD to harden their hearts, that they should come against Israel in battle, that he might destroy them utterly, and that they might have no favour, but that he might destroy them, as the LORD commanded Moses.

But Sihon king of Heshbon would not let us pass by him: for the LORD thy God hardened his spirit, and made his heart obstinate, that he might deliver him into thy hand, as appeareth this day.

Because I knew that thou art obstinate, and thy neck is an iron sinew, and thy brow brass;
