Jeremiah 35:7

Days. The reward of dutiful children, Exodus xx. 12. These are models of those Christians who follow the rule of some virtuous person, in order to be at a greater distance from any transgression of the law, and to observe it with more perfection. (Calmet) --- "If a father could lay such an injunction on his descendants, and they receive commendation for observing it, why may not the fathers of the Church enjoin things which are not of themselves necessary, but....useful to avoid the occasions of evil, or to advance in virtue?" says Grotius, a Protestant, after St. Jerome, (Ad Paulin.) St. Augustine, in Psalm lxx., &c.) (Haydock) Jonadab exhorted, and prescribed this rule, but it was not properly a command, being too arduous. (Tirinus)
