v1-2: The covenant remembered, the two-way agreement; the Lord promised to bless, and Israel promised to obey.
v3: The curse was part of the original covenant. If the people failed to obey, they would be cursed. See, for example, Deuteronomy 28. King Josiah had re-stated the covenant before the people, 2 Kings 23.2-3; perhaps Jeremiah is here underlining the importance of obedience to all that God had said.
v4: Deliverance from Egypt brought the people into relationship with God; and the emphasis of that relationship was obedience, see 7.22-23. But Israel's obedience would bring abundant blessings, "You will be my people, and I will be your God."
v5: God's part of the promise included bringing the people into the promised land, the land flowing with milk and honey. Even as Jeremiah spoke, the people were living in the good of that. The Lord God had planted the people there, see v17.
v6-7: The message of Jeremiah challenged the people to re-enter the covenant with God. By this means their persistent disobedience would be ended.
v8: Even in their early years following the exodus from Egypt, the people had begun to disobey. God had punished them then. He here reminded them that judgment was always part of the covenant. He had brought them into the land, in fulfilment of His promise, and He would punish them also in fulfilment of His promise.
v9-10: The conspiracy among the people, their deliberate decision to return to past sins.
v11-12: Their prayers would not be answered. The true God would refuse to listen to them. The false gods were unable to listen to them.
v13: The multitude of idols, as in 2.28.
v14: Even Jeremiah was commanded not to pray for the people. The judgment announced could not be averted.
v15: The people were committed to evil, planning evil schemes, rejoicing in evil; contrast 1 Cor 13.6.
v16: The olive tree of Israel, previously beautiful and thriving, but now about to be burned and broken.
v17: Idolatry is evil, 'which they have done against themselves' (RAV). Sin dishonours God, and it depraves people.
v18-23: The plot against Jeremiah. He met opposition because he proclaimed God's word. The people devised schemes to silence him. There are a series of complaints that Jeremiah brings before God; 15.10-21; 17.14-18; 18.18-23; and 20.7-18.
v18: The Lord revealed their scheme to him, to protect him, and to allow him to escape.
v19: It seems that Jeremiah, in his innocence, was ignorant of their schemes. They had planned to destroy him, so that his message would be silenced.
v20: Jeremiah invited the Lord to vindicate His Name, and show His righteousness. His confidence was in the God of perfect righteousness, who searches heart and mind.
v21-23: The men were in Anathoth, where Jeremiah lived (1.1; Josh 21.18). The promised remnant would not include them, for all would bear their guilt and sins. It is thought that the people of Anathoth were descendants of Abiathar, who was dismissed as priest by Solomon (1 Kings 2.26-27).
