Baruch (as appeareth from Jer_36:4,26) was a scribe, and an attendant upon Jeremiah, and one who wrote things for him, and from his mouth. He made this purchase with all the usual formalities; to make it public, he signed and sealed it before witnesses, and delivered it to Baruch, to keep in the presence of them all, and in the presence of the Jews who casually were in the place when the thing was done.
