The letter is sent with Elasah and Gemariah, messengers of King Zedekiah, to the elders, priests, prophets and all the people Nebuchadnezzar carried into exile. The Lord tells them to build houses and live in them, plant gardens and eat their fruit, marry and have children, and seek the peace of the city where they are and pray for it, because in its peace they will have peace. The diviners and prophets who deceive them were not sent by God.
The Lord promises that when seventy years are completed for Babylon, he will visit them and bring them back. His thoughts toward them are of welfare and not of evil, to give them a future and a hope. If they seek him with all their heart they will find him, and he will gather them from all the places where he scattered them. Meanwhile two false prophets, Ahab son of Kolaiah and Zedekiah son of Maaseiah, will be handed over to Nebuchadnezzar, who will put them to death, and their end will become a curse.
The chapter closes with Shemaiah the Nehelamite, who writes letters from Babylon to the priest Zephaniah demanding that he rebuke Jeremiah for writing to the exiles. Zephaniah reads the letter to Jeremiah, and the Lord announces that Shemaiah and his descendants will not see the good God will do for his people, because he preached rebellion.
