Solomon, speaking to us as unto children, observes here how much the comfort of parents, natural, political, and ecclesiastical, depends upon the good behaviour of those under their charge, as a reason, 1. Why parents should be careful to give their children a good education, and to train them up in the ways of religion, which, if it obtain the desired effect, they themselves will have the comfort of it, or, if not, they will have for their support under their heaviness that they have done their duty, have done their endeavour. 2. Why children should conduct themselves wisely and well, and live up to their good education, that they may gladden the hearts of their parents, and not sadden them. Observe, (1.) It adds to the comfort of young people that are pious and discreet that thereby they do something towards recompensing their parents for all the care and pains they have taken with them, and occasion pleasure to them in the evil days of old age, when they most need it; and it is the duty of parents to rejoice in their children's wisdom and well-doing, yea, though it arrive at such an eminency as to eclipse them. (2.) It adds to the guilt of those that conduct themselves ill that thereby they grieve those whom they ought to be a joy to, and are a heaviness particularly to their poor mothers who bore them with sorrow, but with greater sorrow see them wicked and vile.
