Passage 4.18.2
ἦγον μὲν δὴ τὰ Λακεδαιμονίων καὶ ἔφερον ὅ τι καὶ δύναιτο αὐτῶν ἕκαστος, ἑλόντες δὲ σῖτον καὶ βοσκήματα καὶ οἶνον ἀνήλισκον, ἔπιπλα δὲ καὶ ἀνθρώπους ἀπεδίδοσαν χρημάτων· ὥστε καὶ ἐποιήσαντο οἱ Λακεδαιμόνιοι δόγμα, ἅτε τοῖς ἐν τῇ Εἴρᾳ μᾶλλον ἢ σφίσιν αὐτοῖς γεωργοῦντες, τὴν Μεσσηνίαν καὶ τῆς Λακωνικῆς τὴν προσεχῆ, ἕως ἂν πολεμῶσιν, ἐᾶν ἄσπορον.
Indeed, the Messenians were driving away the property of the Lacedaemonians and carrying off whatever each was able; they consumed grain, livestock, and wine whenever they seized it, but furniture and people they exchanged for money. Thus the Lacedaemonians passed a decree—since they seemed rather to be farming for those in Eira than for themselves—that, as long as the war lasted, Messenia and the neighboring parts of Laconia should be left uncultivated.
