John Gill Bible Commentary

So Hanameel mine uncle's son came unto me,.... Freely and voluntarily, of his own accord; though it was determined he should, as it was predicted he would; for God's decrees do not infringe the liberty of the will: this man came from Anathoth, very probably, to Jerusalem, to the place where the prophet was: in the court of the prison, according to the word of the Lord; which had been made known before to Jeremiah: and said unto me, buy my field, I pray thee, that is in Anathoth, which is in the country of Benjamin; it belonged to that tribe: for the right of inheritance is thine; the reversion of this field; it would come to him after the death of his cousin, as being next heir: and the redemption is thine; buy it for thyself; since, if it was sold to another, he, according to law, was obliged to redeem it; and therefore it was much better to buy it at once for himself: then I knew that this was the word of the Lord; that it was the word of the Lord which came to him before, and that it was the will of the Lord that he should make this purchase; since there was such an exact agreement between the prophecy and the event.
