What does Jeremiah 18:13 mean?

if they do that which is evil in my sight, that they not obey my voice, then I will repent of the good with which I said I would benefit them.

“Now therefore, speak to the men of Judah, and to the inhabitants of Jerusalem, saying, ‘Yahweh says: “Behold, I frame evil against you, and devise a plan against you. Everyone return from his evil way now, and amend your ways and your doings.”’

But they say, ‘It is in vain; for we will walk after our own plans, and we will each follow the stubbornness of his evil heart.’”

Will the snow of Lebanon fail from the rock of the field? Will the cold waters that flow down from afar be dried up?

For my people have forgotten me. They have burned incense to false gods. They have been made to stumble in their ways, in the ancient paths, to walk in byways, in a way not built up;

to make their land an astonishment, and a perpetual hissing. Everyone who passes thereby will be astonished, and shake his head.
