12 And I gave the paper to Baruch, the son of Neriah, the son of Mahseiah, before the eyes of Hanamel, the son of my father's brother, and of the witnesses who had put their names to the paper, and before all the Jews who were seated in the place of the armed watchmen.

Matthew Henry's Commentary on Jeremiah 32:12

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.
