Charles Ellicott Commentary Jeremiah 32:8

"So Hanamel mine uncle`s son came to me in the court of the guard according to the word of Jehovah, and said unto me, Buy my field, I pray thee, that is in Anathoth, which is in the land of Benjamin; for the right of inheritance is thine, and the redemption is thine; buy it for thyself. Then I knew that this was the word of Jehovah." — Jeremiah 32:8 (ASV)

Buy my field, I pray thee, that is in Anathoth ... —We are not told what led Hanameel to make the offer of sale. Probably, as in the Assyrian invasion (Isaiah 10:30), Anathoth was occupied and ravaged by the army of the Chaldeans, and the field seemed to its possessor little more than a damnosa hœreditas (“an inheritance of ruin”), which he was glad to get rid of at any price.

Perhaps, too, considering the part that Jeremiah had taken in urging submission to Nebuchadnezzar, it seemed prudent to transfer the ownership of the field to one whom the Chaldeans were disposed to protect, while, since Jeremiah was in prison, Hanameel might well expect to remain in occupation as his representative. The words the right of inheritance is thine indicate that Hanameel had no children. The description Anathoth, which is in the country of Benjamin, hardly natural from one cousin speaking to another, is missing from the Septuagint version and is traceable probably to the Jewish habit of writing in the text what we would consider notes in the margin.
