Matthew Poole's Concise Commentary
Jeremiah 35:19
For ever here signifies the ever of the Jewish state or church; whether the promise relates to the abiding of Jonadab's family, when many families of the Jews were quite rooted out, cut off, and extinct, or to some special favour that God would show them, or to some place of office they should have in or about the temple, (as some judge, because, 1 Chronicles 2:55, it appears they were scribes,) is uncertain. But it is a question of more moment, How God promiseth a reward to these sons of Jonadab for obeying the command of their father, and whether they had sinned if they had not obeyed this command of Jonadab; which brings in another question, Whether parents have a power to oblige their children in matters which God hath left at liberty. To which I answer, 1. God might reward these Rechabites for their reverence and obedience to Jonadab their father, though these were not strictly, by the Divine law, obliged thus far to have obeyed him; as he rewarded David for his thoughts in his heart to build him a house, though it was not God's will that he should do it; so as God's promise of the reward doth not prove their obedience in this particular to have been their duty. Admit that it remained still a matter of liberty, yet the general honour and reverence they testified might be rewarded by God.
2. Unquestionably parents have not a power to determine children in all things as to which God hath left them a liberty, for then they have a power to make their children slaves, and to take away all their natural liberty. To marry or not, and to this or that person, is matter of liberty. Parents cannot in this case determine their children; Bethuel, Genesis 24:58, asketh Rebekah if she would go with Abraham's servant before he would send her. 3. In matters of civil concernment they have a far greater power than in matters of religion. All souls are God s, and conscience can be under no other dominion than that of God. 4. In civil things parents have a great power, during the nonage of children, and after also in matters which concern their parents good, as to command them to assist them, to help to supply their necessities, &c. 5. Parents being set over children, and instead of God to them, as it is their duty to advise their children to the best of their ability for their good; so it is the duty of children to receive their advice, and not to depart from it, unless they see circumstances so mistaken by parents, or so altered by the providence of God, as they may reasonably judge their parents, had these known or foreseen it, would not have so advised. But that parents have an absolute power to determine children in all things as to which God hath not forbidden them, and that children by the law of God are obliged to an obedience to all such commands, however they may see their parents mistaken, or God by his providence may have altered circumstances, I see no reason to conclude. Jonadab had prudently advised his sons as before mentioned; they were things they might do, and which by experience they found not hurtful to them, but of great profit and advantage, and that with reference to all the ends of man's life: herein they yield obedience, and pay a reverence to their parent; this pleaseth God, he promiseth to reward them with the continuance of their family, according to what he had said, Exodus 20:12, in the fifth commandment, which the apostle calleth the first commandment with promise.
