What does Jeremiah 1:12 mean?

Then Yahweh stretched out his hand, and touched my mouth. Then Yahweh said to me, “Behold, I have put my words in your mouth.

Behold, I have today set you over the nations and over the kingdoms, to uproot and to tear down, to destroy and to overthrow, to build and to plant.”

Moreover Yahweh’s word came to me, saying, “Jeremiah, what do you see?” I said, “I see a branch of an almond tree.”

Yahweh’s word came to me the second time, saying, “What do you see?” I said, “I see a boiling cauldron; and it is tipping away from the north.”

Then Yahweh said to me, “Out of the north, evil will break out on all the inhabitants of the land.

For, behold, I will call all the families of the kingdoms of the north,” says Yahweh. “They will come, and they will each set his throne at the entrance of the gates of Jerusalem, and against all its walls all around, and against all the cities of Judah.
