Did Hizkiyahu king of Judah
and all Judah execute him? Prophecies of this kind have been heard before,
several generations previously. Then, too, people were not overjoyed to hear
those statements, but they did not harm the prophet. Rather, didn’t he, King
Hizkiyahu, fear the Lord and plead before the Lord in this very Temple?
And the Lord reconsidered the evil that He spoke against them. And if we
act differently, we are performing great evil against our souls, all the
more so if we actively harm the prophet. (source)
