Matthew Henry's Concise Commentary

35:12-19 The trial of the Rechabites' constancy was for a sign; it made the disobedience of the Jews to God the more marked. The Rechabites were obedient to one who was but a man like themselves, and Jonadab never did for his seed what God has done for his people. Mercy is promised to the Rechabites. We are not told respecting the performance of this promise; but doubtless it was performed, and travellers say the Rechabites may be found a separate people to this day. Let us follow the counsels of our pious forefathers, and we shall find good in so doing.
