What does Jeremiah 32:7 mean?

and Zedekiah king of Judah won’t escape out of the hand of the Chaldeans, but will surely be delivered into the hand of the king of Babylon, and will speak with him mouth to mouth, and his eyes will see his eyes;

and he will bring Zedekiah to Babylon, and he will be there until I visit him,” says Yahweh: “though you fight with the Chaldeans, you will not prosper?”’”

Jeremiah said, “Yahweh’s word came to me, saying,

“So Hanamel my uncle’s son came to me in the court of the guard according to Yahweh’s word, and said to me, ‘Please buy my field that is in Anathoth, which is in the land of Benjamin; for the right of inheritance is yours, and the redemption is yours. Buy it for yourself.’ “Then I knew that this was Yahweh’s word.

I bought the field that was in Anathoth of Hanamel my uncle’s son, and weighed him the money, even seventeen shekels of silver.

I signed the deed, sealed it, called witnesses, and weighed the money in the balances to him.
