LXX Deut 15:9

πρόσεχε σεαυτῷ μὴ γένηται ῥῆμα κρυπτὸν ἐν τῇ καρδίᾳ σου, ἀνόμημα, λέγων Ἐηίζει τὸ ἔτος τὸ ἕβδομον, ἔτος τῆς ἀφέσεως, καὶ πονηρεύσηται ὁ ὀφθαλμός σου τῷ ἀδελφῷ σου τῷ ἐπιδεομένῳ, καὶ οὐ δώσεις αὐτῷ, καὶ καταβοήσεται κατὰ σοῦ πρὸς κύριον, καὶ ἔσται ἐν σοὶ ἁμαρτία μεγάλη.

Be careful not to harbor this wicked thought in your heart: “The seventh year, the year of release, is near,” so that you look upon your poor brother begrudgingly and give him nothing. He will cry out to the LORD against you, and you will be guilty of sin.
