What is happening in this passage where God speaks of a new covenant?

In this passage, God is speaking to His people after a long season of judgment. They have been torn down because of their sin, but now God promises a different future. He says He will watch over them to build and to plant, not just to uproot and destroy. He will multiply people and animals again in the land. God also corrects a common saying that blamed ancestors for present trouble, and instead stresses personal responsibility for sin. At the center, He promises a new covenant, where His law will be written on hearts, their sins will be forgiven, and they will truly know Him.

What does the proverb about sour grapes and children’s teeth mean here?

The saying about fathers eating sour grapes and children’s teeth being set on edge was a way people talked about suffering for the sins of earlier generations. They were basically saying, “Our fathers sinned, and we are the ones paying for it.” God answers this by saying that in the days to come, this proverb will no longer be used. Instead, everyone will answer for their own sin. “Every man that eats the sour grape, his teeth shall be set on edge.” This shifts the focus from blaming the past to facing personal responsibility before God and seeking Him for mercy.

What does God mean when He says He will make a new covenant?

God explains that this new covenant will not be like the one made when He brought Israel out of Egypt, which they broke even though He cared for them like a husband. The new covenant is different in kind. Instead of relying on external commands written on stone, God says He will put His law within them and write it on their hearts. He will be their God and they will be His people in a deeper way. This covenant is based on His grace and His work inside people, changing them so they truly know Him and live for Him.

What does it mean that God writes His law in their hearts?

When God says He will put His law in their inward parts and write it in their hearts, He is talking about an inner work, not just outward rules. Before, the law was written on tablets and could be known only from the outside. In the new covenant, God Himself changes people within, so they have a real desire to follow Him. Obedience becomes something that comes from the heart. This includes faith, love for God, and a new will that agrees with His ways. It is the picture of God giving His Spirit so that His people not only know His commands but want to walk in them.

Why does the passage say they will not teach each other to know the Lord?

God says that under this new covenant, they will not say to each other, “Know the Lord,” because they will all know Him, from the least to the greatest. This does not mean that no one will ever teach again, but that the knowledge of God will be real and personal for every member of His people. Instead of many being in the dark or only knowing God on the surface, all will be brought into a close relationship with Him. This comes together with His promise to forgive their sins and remember them no more, which opens the way for this deep, shared knowledge of God.

What does this passage teach about God’s forgiveness of sin?

This passage gives a clear promise about forgiveness. God says, “I will forgive their iniquity, and I will remember their sin no more.” That does not mean He forgets as we do, but that He will no longer treat them according to those sins. The guilt that separated them from Him will be taken away. This forgiveness is not shallow or temporary. It is tied to the new covenant, where God changes hearts and restores the relationship. The people had broken the earlier covenant, but here God shows that He is ready to wipe out their sins and welcome them again as His own.

How does God show in this passage that He will never give up on His people?

God points to the sun, moon, stars, and the sea to make His point. He reminds them that He is the One who set the sun to shine by day and the moon and stars by night, and who rules the restless sea. Then He says that if those set orders could fail, then Israel could cease to be a nation before Him. He also says that only if heaven could be measured and the foundations of the earth fully searched out would He cast off all the seed of Israel. These pictures show how sure His promise is. His faithfulness to His people is tied to the stability of creation itself.

What is the meaning of the promise to rebuild the city and make it holy?

Near the end of the passage, God speaks of days coming when the city will be built to Him, from the tower of Hananeel to the corner gate, with the measuring line going over hill Gareb and around to Goath. Even the valley of dead bodies and ashes, and the fields down to the brook Kidron and toward the horse gate, will be holy to the Lord. This shows that places that had seen judgment and uncleanness would be included in the restored, holy city. The city will not be plucked up or thrown down any more. It is a picture of full restoration, safety, and a community set apart for God.

How can this promise of a new covenant encourage believers today?

This passage encourages believers by showing that God does not leave His people in their failure. The earlier covenant was broken, but God promises a new one where He Himself changes hearts, gives true knowledge of Him, and forgives sins completely. When someone feels weighed down by past disobedience or fearful that God is finished with them, these words remind them that God’s plan centers on mercy and renewal. The same God who watched over His people to tear down also watches to build and plant. His faithfulness, tied to the steady sun and stars, gives strong comfort to those who trust His promises.

Why might some readers find the wording of this passage difficult to understand?

Some parts can feel hard because they use old sayings and strong images. The sour grapes proverb, the talk of a new covenant unlike the old, and the detailed place names can seem distant at first. Also, God speaks both of past judgment and future blessing in the same breath, which can be confusing. Faithful readers have seen this passage as pointing both to the return from exile and to later, fuller blessings, so there is depth packed into a few lines. Taking time to notice that the main thread is God’s steady, merciful plan to restore and renew His people helps bring the pieces together.

The New Covenant

Upon this I awaked, and beheld; and my sleep was sweet unto me.

¶ Behold, the days come, saith the Lord, that I will sow the house of Israel and the house of Judah with the seed of man, and with the seed of beast.

And it shall come to pass, that like as I have watched over them, to pluck up, and to break down, and to throw down, and to destroy, and to afflict; so will I watch over them, to build, and to plant, saith the Lord.

In those days they shall say no more, The fathers have eaten a sour grape, and the children’s teeth are set on edge.

But every one shall die for his own iniquity: every man that eateth the sour grape, his teeth shall be set on edge.

¶ 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:

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:

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.

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.

¶ Thus saith the Lord, which giveth the sun for a light by day, and the ordinances of the moon and of the stars for a light by night, which divideth the sea when the waves thereof roar; The Lord of hosts is his name:

If those ordinances depart from before me, saith the Lord, then the seed of Israel also shall cease from being a nation before me for ever.

Thus saith the Lord; If heaven above can be measured, and the foundations of the earth searched out beneath, I will also cast off all the seed of Israel for all that they have done, saith the Lord.

¶ Behold, the days come, saith the Lord, that the city shall be built to the Lord from the tower of Hananeel unto the gate of the corner.

And the measuring line shall yet go forth over against it upon the hill Gareb, and shall compass about to Goath.

And the whole valley of the dead bodies, and of the ashes, and all the fields unto the brook of Kidron, unto the corner of the horse gate toward the east, shall be holy unto the Lord; it shall not be plucked up, nor thrown down any more for ever.
