LXX Deut 17:8

Ἐὰν δὲ ἀδυνατήσῃ ἀπὸ σοῦ ῥῆμα ἐν κρίσει ἀνὰ μέσον αἷμα αἵματος, καὶ ἀνὰ μέσον κρίσις κρίσεως, καὶ ἀνὰ μέσον ἁφὴ ἁφῆς, καὶ ἀνὰ μέσον ἀντιλογία ἀντιλογίας, ῥήματα κρίσεως ἐν ταῖς πόλεσιν ὑμῶν· καὶ ἀναστὰς ἀναβήσῃ εἰς τὸν τόπον ὃν ἂν ἐκλέξηται Κύριος ὁ θεός σου ἐκεῖ,

If a case is too difficult for you to judge, whether the controversy within your gates is regarding bloodshed, lawsuits, or assaults, you must go up to the place the LORD your God will choose.
