“Thus will my anger be accomplished, and I will satisfy my fury on them, and I will be comforted. And they will know that I, Yahweh have spoken in my zeal, when I have accomplished my fury on them.”
Outwardly all the results were natural results, and came about through rebellion against Nebuchadnezzar. It was not God Who starved them. It was not God Who slew them. It was not God Who turned them to cannibalism. Yet He was the cause for He had withdrawn His protecting hand from them, because by their sins they had rejected His covenant and take themselves from under His protection. As ever in Scripture, this anger was not bad temper and vengeance because He was slighted, but the result of His holy response to what was detestable. He could not allow it to exist in those whom He had chosen and had to take every opportunity to get rid of it by judgment and refining.
‘I will satisfy (appease) My fury.' He would call to account and give a just sentence so as to satisfy His moral demands. ‘I will be comforted.' His hatred at sin would be appeased by a just reward for sin, as the Moral Governor of the Universe.
‘In My zeal.' The ardour of a holy God against sin. The word is sometimes translated jealousy. There too it means the same.
