Jeremiah 35:2 - Matthew Poole's English Annotations on the Holy Bible

These Rechabites had their name from Rechab their father, who, as appears from 1 Chronicles 2:55, descended from Hemath, who was a Kenite, who is also called Hobab, Judges 4:11 (unless it may be Hameth who was the son of Hobab). This Hobab was Jethro, the father-in-law of Moses, as appears from Judges 4:11. We read, Judges 1:16, that his children went up out of the city of palm trees with the children of Judah, which lieth in the south of Arad, and they went and dwelt among the people. The Rechabites here mentioned descended from this stock. Jehonadab, mentioned 2 Kings 10:15, was of this family, a man of some note, as appeareth by Jehu's taking him there into his chariot. God commandeth the prophet to bring some of this family into the temple, into some of the chambers; for in and about the temple were several chambers for the priests, and where they disposed of the holy garments and several oblations, 1 Kings 6:5,6,10 1 Chronicles 28:11,12. God commands Jeremiah to bring these Rechabites into some of these chambers, and to set wine before them. This was either for the more publicness of the thing, or, it may be, for the reproof of the priests who drank too much wine.
