Prophesying lies in the Name of the Lord

Look what happened to Hananiah after giving a false prophecy in the Name of the Lord:

“Thus speaks the Lord of hosts, the God of Israel, saying: ‘I have broken the yoke of the king of Babylon. Within two full years I will bring back to this place all the vessels of the Lord’s house, that Nebuchadnezzar king of Babylon took away from this place and carried to Babylon. And I will bring back to this place Jeconiah the son of Jehoiakim, king of Judah, with all the captives of Judah who went to Babylon,’ says the Lord, ‘for I will break the yoke of the king of Babylon.’”

Then Hananiah the prophet took the yoke off the prophet Jeremiah’s neck and broke it. And Hananiah spoke in the presence of all the people, saying, “Thus says the Lord: ‘Even so I will break the yoke of Nebuchadnezzar king of Babylon from the neck of all nations within the space of two full years.’” And the prophet Jeremiah went his way.

Now the word of the Lord came to Jeremiah, after Hananiah the prophet had broken the yoke from the neck of the prophet Jeremiah, saying, “Go and tell Hananiah, saying, ‘Thus says the Lord: “You have broken the yokes of wood, but you have made in their place yokes of iron.” For thus says the Lord of hosts, the God of Israel: “I have put a yoke of iron on the neck of all these nations, that they may serve Nebuchadnezzar king of Babylon; and they shall serve him. I have given him the beasts of the field also.”’”

Then the prophet Jeremiah said to Hananiah the prophet, “Hear now, Hananiah, the Lord has not sent you, but you make this people trust in a lie. Therefore thus says the Lord: ‘Behold, I will cast you from the face of the earth. This year you shall die, because you have taught rebellion against the Lord.’”

So Hananiah the prophet died the same year in the seventh month."

Just sayin'. Be careful to speak a word in the Name of the Lord when it is not from Him.
