6 And Jeremiah said, The word of Jehovah came unto me, saying, 7 Behold, Hanamel the son of Shallum thine uncle shall come unto thee, saying, Buy thee my field that is in Anathoth; for the right of redemption is thine to buy it. 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. 9 And I bought the field that was in Anathoth of Hanamel mine uncle's son, and weighed him the money, even seventeen shekels of silver.

Commentary on Jeremiah 32:1-15
(Read Jeremiah 32:1-15)
Jeremiah, being in prison for his prophecy, purchased a piece of ground. This was to signify, that though Jerusalem was besieged, and the whole country likely to be laid waste, yet the time would come, when houses, and fields, and vineyards, should be again possessed. It concerns ministers to make it appear that they believe what they preach to others. And it is good to manage even our worldly affairs in faith; to do common business with reference to the providence and promise of God.
