v1-6: The word to religious people, those who came to worship in the Lord's house; but also to "all the people." These people should have set an example for all the nations, and be a witness to surrounding nations. Jeremiah had a responsibility, "Do not omit a word," an indication that this message would be difficult to bring.
Only 15 years earlier, Josiah had repaired the temple, and the people had, apparently, turned back to the Lord. This shows how fickle the human heart can be, in betraying their previous loyalty. If the people maintained their disobedience, then they would suffer God's judgment. Although the people were persistent in their sin, God was persistent in sending His prophets to speak to them.
v7-9: "They will fight against you," (1.19) fulfilled here. Jeremiah proclaimed the unpopular message, and humanly he was alone. His words were unacceptable to the religious leaders, prophets and priests. And all the people gathered against him.
v10-11: The princes of Judah heard about the incident, and came to investigate. The prophets and priests said that Jeremiah deserved to die. At the time of the Lord Jesus, a similar debate occurred.
v12-15: Jeremiah's defence was simple, "The Lord sent me." He was faithful to his calling. He remained genuinely concerned for the people, urging them to repent, so that the threatened judgment would be averted. He had no doubt that God's judgment would fall if the people persisted in their rebellion against God.
Jeremiah considered himself dispensable, "Do with me whatever you think is good and right." He was willing to "decrease" as long as God was honoured. However, if they did kill him, that would be more innocent blood, and would indicate their refusal to repent. Stephen manifested the same character (Acts 7.59-60).
v16-19: Surprisingly Jeremiah found support from some of the princes, officials. They recognised that Jeremiah was bringing the message of truth. The reference is to Mic 3.12; Micah was a contemporary of Isaiah. Jeremiah also found support from the elders. There is always conflict, when the prophet brings the word of God to a disobedient people.
v20-23: It seems the testimony of Uriah (Urijah) was also recalled, although he had been put to death for his testimony.
v24: Jeremiah also found support from Ahikam, evidently an influential leader. . Jeremiah may have felt alone in his ministry, but he stood in a line of faithful men and women bringing the word of God.
