Charles Ellicott Commentary Jeremiah 26:9

"Why hast thou prophesied in the name of Jehovah, saying, This house shall be like Shiloh, and this city shall be desolate, without inhabitant? And all the people were gathered unto Jeremiah in the house of Jehovah." — Jeremiah 26:9 (ASV)

Why hast thou prophesied in the name of the Lord ...? —The threat that the house in which they gloried should be like the old sanctuary of Ephraim, over whose fall they had exulted, was like the last drop that made the cup of wrath and bitterness run over. They had chanted their psalms, which told how God forsook the tabernacle of Shiloh, even the tent which He had pitched among men (Psalms 78:60). They could not bear to hear that a similar fate was impending over them.
