In the Septuagint, the Greek word for “blessing” is eulogeo, and the Greek word for “cursing” is katara. Both of these words are used, for example, in Deuteronomy 30:19. After he gives the people the Law, Moses tells the people, “I call heaven and earth to witness against you today, that I have set before you life and death, the blessing (Greek eulogeo) and the curse (Greek katara)…” (LXX) Thus, the blessing and cursing of God is dispensed by the keeping of the Law. Paul’s enemies in Galatia would have known of this concept.
