New Defender's Study Bible Notes
32:14 evidence of the purchase. By purchasing this field, even when he was in prison and the Babylonian army was occupying the field, and even knowing that the Jews would all be in exile for seventy years, Jeremiah demonstrated his own faith in God’s word, which had promised their eventual return and repossession of the land.
32:14 evidence which is open. The evidence of ownership (title deed) was in the form of a scroll describing the property and the transaction, with the owner’s name and property description written on both the outside of the scroll and, under seal, on the inside as well. The seal could be broken and the property claimed only by the owner whose name was on the outside. Compare Revelation 5:1-10.
