Jeremiah 35:12-16

Then came the word of the Lord unto Jeremiah As the trial of the constancy of the Rechabites was only intended for a sign, so now we have the application of it made by God himself. Tell the men of Judah, Will ye not receive instruction? &c. Will nothing enlighten or affect you? Will nothing prevail to make you sensible of your sin and duty? You see how obedient the Rechabites are to their father's commandment; but you have not hearkened unto me Though it might have been more reasonably expected that my people should have obeyed me, than that the sons of Jonadab should have obeyed him. Thus the Rechabites' observance of their father's charge to them is made use of by God as an aggravation of the disobedience of the Jews to him: and the aggravation was certainly very high. For, 1st, The Rechabites were obedient to one that was but a man like themselves, and had only the wisdom and power of a man, and was only the father of their flesh; but the Jews were disobedient to the infinite and eternal God, that had an absolute authority over them, as the father of their spirits. 2d, Jonadab was long since dead, and was ignorant of his posterity, and could neither take cognizance of their disobedience to his orders, nor give any correction for it; but God lives for ever to see how his laws are observed, and is in readiness to punish all disobedience. 3d, The Rechabites were probably seldom or never put in mind of their obligations to their progenitor; but God often sent his prophets to his people, to remind them of, and excite to, their duty to him, yet they would not comply with it. This is insisted on here as a great aggravation of their disobedience, Jeremiah 35:14; Jer 15:4 th, Jonadab had not conferred, nor could confer, any such favours on his seed as God had bestowed on his people, nor had laid them under any such obligations, from duty and interest, to obey him, as God had laid Israel and Judah under to observe his laws. 5th, God did not oblige his people to so much hardship, and to such instances of self-denial and mortification, as Jonadab enjoined to his seed, and yet Jonadab's orders, were obeyed, and God's were not.
