John Trapp on Jeremiah 32:7

Ver. 7. Behold Hanameel the ſon of Shallum] This Shallum, and Hilkiah the Father of Jeremiah, were brethren. And it was no leſſe an honour to Hanameel to have ſuch a kinſman as Jeremy, then afterwards it was to Mark to be Barnabas his ſiſters ſon.

Buy thee my field that is in Anathoth] The Prieſts, though they had no corn-fields, yet they had meadows for their cattle, gardens and orchards in the ſuburbs of their Cities: which in ſome caſes they might ſell one to another, till the year of Jubilee howſoever. Some ſay that if ſuch a field were ſo ſold to a kinſman, as here, it remained to him for ever. But the poſſeſſion of the Levites might at any time be redeemed, Lev. 25.32.

For the right of redemption is thine] See Levit. 25.25, 32.Ruth 3.12. & 4.3, 4.
