Charles H. Spurgeon on Psalms 132:12

Their children shall also sit upon thy throne for evermore. As if he had said, this promise as touching Christ will I accomplish, and will undoubtedly establish the throne unto my servant David; but do not ye, which in the meantime sit on this throne, and govern this kingdom, presume upon the promise, and think that you cannot err, or that I will wink at your errors, and not rather condemn and severely punish them. Therefore either govern your kingdom according to my word, or else I will root you out and destroy you for ever. This promise he now amplifies, and setteth forth more at large. —Martin Luther.
