The LORD calls Jeremiah to be a prophet and gives him messages to deliver to Israel and Judah. Jeremiah is told to warn the people that they will be punished for rejecting God and worshipping false idols. God promises to one day make a new covenant with Israel where he will write his law on the people's hearts so they will all know him directly. The nation will be punished with exile in Babylon for 70 years but then God will restore the people to their land.
