Yehoyachin king of Yehudah, came out to the king of Bavel. That he do to him as he wishes, and not for war.⁶Nevuchadnetzar, at this time, did not come to destroy Yerusholayim. He only demanded that Yehoyachin be handed over to him. See Vayikra Rabboh 19:6.

And Jehoiachin the king of Judah went out to the king of Babylon: This means that he went out during the King of Babylon's siege, when they heard that he had come there, to make peace with him and to place his neck under his yoke. But he (the King of Babylon) didn't want to make peace with him, so he exiled him to Babylon - him, and his mother, and his servants, and his princes, and his officers, in the eighth year of rather reign of Nebuchadnezzar, King of Babylon - seven full years had passed for him.
