Ecclesiastes 1:10-11 (nothing new):
10 Is there a thing of which it is said, “See, this is new”? It has been already in the ages before us.
11 There is no remembrance of former things, nor will there be any remembrance of later things yet to be among those who come after.
But God will bring something new:
8 I am the LORD; that is my name; my glory I give to no other, nor my praise to carved idols.
9 Behold, the former things have come to pass, and new things I now declare; before they spring forth I tell you of them.”
6 “You have heard; now see all this; and will you not declare it? From this time forth I announce to you new things, hidden things that you have not known.
7 They are created now, not long ago; before today you have never heard of them, lest you should say, ‘Behold, I knew them.’
8 You have never heard, you have never known, from of old your ear has not been opened. For I knew that you would surely deal treacherously, and that from before birth you were called a rebel.
A new heart and spirit:
30 “Therefore I will judge you, O house of Israel, every one according to his ways, declares the Lord GOD. Repent and turn from all your transgressions, lest iniquity be your ruin.
31 Cast away from you all the transgressions that you have committed, and make yourselves a new heart and a new spirit! Why will you die, O house of Israel?
32 For I have no pleasure in the death of anyone, declares the Lord GOD; so turn, and live.”
A new covenant:
31 “Behold, the days are coming, declares the LORD, when I will make a new covenant with the house of Israel and the house of Judah,
32 not like the covenant that I made with their fathers on the day when I took them by the hand to bring them out of the land of Egypt, my covenant that they broke, though I was their husband, declares the LORD.
33 But this is the covenant that I will make with the house of Israel after those days, declares the LORD: I will put my law within them, and I will write it on their hearts. And I will be their God, and they shall be my people.
Jeremiah 31:31-33. A new heaven and earth:
16 So that he who blesses himself in the land shall bless himself by the God of truth, and he who takes an oath in the land shall swear by the God of truth; because the former troubles are forgotten and are hidden from my eyes.
17 “For behold, I create new heavens and a new earth, and the former things shall not be remembered or come into mind.
18 But be glad and rejoice forever in that which I create; for behold, I create Jerusalem to be a joy, and her people to be a gladness.
19 I will rejoice in Jerusalem and be glad in my people; no more shall be heard in it the sound of weeping and the cry of distress.
Isaiah 65:15-19. Note that the forgetfulness which is an evil in Ecclesiastes 1 will become a blessing when the world passes away and the new world comes.
