LXX Deut 20:19

Ἐὰν δὲ περικαθίσῃς περὶ πόλιν μίαν ἡμέρας πλείους ἐκπολεμῆσαι αὐτὴν εἰς κατάλημψιν αὐτῆς, οὐχὶ ἐξολεθρεύσεις τὰ δένδρα αὐτῆς ἐπιβαλεῖν ἐπ’ αὐτὰ σίδηρον. ἀλλ’ ἢ ἀπ’ αὐτοῦ φάγῃ, αὐτὸ δὲ οὐκ ἐκκόψεις. μὴ ἄνθρωπος τὸ ξύλον τὸ ἐν τῷ ἀγρῷ, εἰσελθεῖν ἀπὸ προσώπου σου ἐς τὸν χάρακα,.

When you lay siege to a city for an extended time while fighting against it to capture it, you must not destroy its trees by putting an axe to them, because you can eat their fruit. You must not cut them down. Are the trees of the field human, that you should besiege them?
