What does Jeremiah 32:7 mean?

Then God spoke to me: 'Your cousin Hanamel, son of Shallum, is going to come and say, “Buy my field at Anathoth, because as next of kin, you have the right to buy it.”' Jeremiah 32:7 - Modern Text Bible

(God tells Jeremiah that his cousin will offer him a chance to buy family land, which is a legal right in their culture.)
