Whether a man is bound to immediate restitution, or may he put it off?

Objections

Objection 1 : It would seem that a man is not bound to immediate restitution, and can lawfully delay to restore. For affirmative precepts do not bind for always. Now the necessity of making restitution is binding through an affirmative precept. Therefore a man is not bound to immediate restitution.
Objection 2 : Further, no man is bound to do what is impossible. But it is sometimes impossible to make restitution at once. Therefore no man is bound to immediate restitution.
Objection 3 : Further, restitution is an act of virtue, viz. of justice. Now time is one of the circumstances requisite for virtuous acts. Since then the other circumstances are not determinate for acts of virtue, but are determinable according to the dictate of prudence, it seems that neither in restitution is there any fixed time, so that a man be bound to restore at once.
