Plato, Laws 913b

εὑρεῖν ποτε θεοῖς εὐξαίμην μήθʼ εὑρὼν κινήσαιμι, μηδʼ αὖ τοῖς λεγομένοις μάντεσιν ἀνακοινώσαιμι τοῖς ἁμῶς γέ πώς μοι συμβουλεύουσιν ἀνελεῖν τὴν γῇ παρακαταθήκην. οὐ γάρ ποτε τοσοῦτον εἰς χρημάτων ὠφεληθείην ἂν κτῆσιν ἀνελών, ὅσον εἰς ὄγκον πρὸς ἀρετὴν ψυχῆς καὶ τὸ δίκαιον ἐπιδιδοίην μὴ ἀνελόμενος, κτῆμα ἀντὶ κτήματος ἄμεινον ἐν ἀμείνονι κτησάμενος, δίκην ἐν τῇ ψυχῇ πλούτου προτιμήσας ἐν οὐσίᾳ κεκτῆσθαι πρότερον· ἐπὶ πολλοῖς γὰρ δὴ λεγόμενον εὖ τὸ μὴ κινεῖν τὰ ἀκίνητα καὶ περὶ τούτου

nor, if I do find it, may I move it, nor may I ever tell of it to the soothsayers (so-called), who are certain to counsel me to take up what is laid down in the ground. For never should I gain so much pecuniary profit by its removal, as I should win increase in virtue of soul and in justice by not removing it; and by preferring to gain justice in my soul rather than money in my purse, I should be winning a greater in place of a lesser gain, and that too in a better part of me. The rule, Thou shalt not move the immovable, is rightly applicable to many cases; and the case before us is one of them.
