Hesiod

Εἰ γάρ κεν καὶ σμικρὸν ἐπὶ σμικρῷ καταθεῖο
καὶ θαμὰ τοῦτ᾽ ἔρδοις, τάχα κεν μέγα καὶ τὸ γένοιτο.

Ἠδ᾽ Ἔρος, ὃς κάλλιστος ἐν ἀθανάτοισι θεοῖσι,
λυσιμελής, πάντων δὲ θεῶν πάντων τ᾽ ἀνθρώπων
δάμναται ἐν στήθεσσι νόον καὶ ἐπίφρονα βουλήν.

Ὣς οὐκ ἔστι Διὸς κλέψαι νόον οὐδὲ παρελθεῖν.

He is a fool who tries to withstand the stronger, for he does not get the mastery and suffers pain besides his shame.

Πίστεις ἄρ τοι ὁμῶς καὶ ἀπιστίαι ὤλεσαν ἄνδρας.

Work the work which the gods ordained for men, lest in bitter anguish of spirit you with your wife and children seek your livelihood amongst your neighbours, and they do not heed you.

Wealth should not be seized: god-given wealth is much better.

Let it please thee to keep in order a moderate-sized farm, that so thy garners may be full of fruits in their season.
