What does Jeremiah 26:7 mean?

You shall tell them, “Yahweh says: ‘If you will not listen to me, to walk in my law, which I have set before you,

to listen to the words of my servants the prophets, whom I send to you, even rising up early and sending them, but you have not listened;

then I will make this house like Shiloh, and will make this city a curse to all the nations of the earth.”’”

When Jeremiah had finished speaking all that Yahweh had commanded him to speak to all the people, the priests and the prophets and all the people seized him, saying, “You shall surely die!

Why have you prophesied in Yahweh’s name, saying, ‘This house will be like Shiloh, and this city will be desolate, without inhabitant?’” All the people were crowded around Jeremiah in Yahweh’s house.

When the princes of Judah heard these things, they came up from the king’s house to Yahweh’s house; and they sat in the entry of the new gate of Yahweh’s house.
