New Defender's Study Bible Notes
32:8 redemption is thine. Note Leviticus 25:25. Jeremiah’s home and relatives (all, like he, being Levites) were in Anathoth, so that he would have a kinsman’s right to buy the land that was in danger of being lost to someone outside the family and tribe.
32:11 that which was open. The title document was to be set forth in detail on the inside of the scroll, then sealed, then a briefer summary of the transaction inscribed on the outside. See notes on Revelation 5:1,2; also that on Jeremiah 32:14.
32:12 Baruch the son of Neriah. Baruch, first mentioned here, was a friend and scribe to Jeremiah (Jeremiah 36:4,32).
