3 Go meet with the messengers from Edom, Moab, Ammon, Tyrus, and Zidon, who are in Jerusalem visiting King Zedekiah. 4 Tell them to say this to their kings:
6 I've given your land and everything on earth to my servant Nebuchadnezzar of Babylon. Your animals must serve him too.
7 All the nations on earth will serve him, and his son, and his son's son.
8 I’ll punish any nation who refuses to serve him (by putting his yoke on their neck) with war, famine, and disease until I've killed everyone in that nation.
9 So don't listen to anyone (prophet, diviner, dreamer, enchanter, or sorcerer) who tells you that you won't serve the king of Babylon.
10 They're lying to you. If you believe them, I'll kill you.
11 If you put the yoke of the king of Babylon on your neck and serve him, I'll let you and your people live.
15 A voice will be heard in Ramah. Rachel will be weeping for her dead children.
29 In those days, they'll no longer say, “The father eats a sour grape, and the children's teeth are set on edge,” but everyone will die for their own iniquity.
40 And the valley of the dead bodies will be holy to me.
A few more words about this episode
In the beginning of King Zedekiah's reign (27:1)
The King James Version says King Jehoiakim, but most modern translations replace Jehoiakim, which is in the Hebrew text, with Zedekiah, which is in most Hebrew translations -- since the context makes it clear that Zedekiah is intended. (See Wikipedia: Jeremiah 27:1) -- which would make it 597 BCE.
Ahab and Zedekiah
Not the king of Israel or the minor prophet, but just two unfortunate guys with hopeful prophecies like those of Hananiah. God had them burned alive by Nebuchadnezzar.
