10 All who rely on observing the law are under a curse, for it is written: "Cursed is everyone who does not continue to do everything written in the Book of the Law." [a] 11 Clearly no one is justified before God by the law, because "the righteous will live by faith." [b] 12 The law is not based on faith; on the contrary, it says, "Whoever does these things will live by them." [c] 13 Christ redeemed us from the curse of the law by becoming a curse for us, for it is written: "Cursed is everyone who is hung on a pole." [d] 14 He redeemed us in order that the blessing given to Abraham might come to the Gentiles through Christ Jesus, so that by faith we might receive the promise of the Spirit. (TNIV).
a. Galatians 3:10 Deut. 27:26
b. Galatians 3:11 Hab. 2:4
c. Galatians 3:12 Lev. 18:5
d. Galatians 3:13 Deut. 21:23
Moyise schematizes Andrew Das' argument as follows:
1. Dt. 27.26 rightly threatens a curse to all who do not keep the law.
2. It is evident that no one keeps the law perfectly.
3. Hence, everyone is under a curse.
4. Lev. 18.5 promises life to those who keep the law.
5. It is evident that no one keeps the law perfectly.
6. Hence, no one receives life through the law.
Second, whereas Paul’s cites Hab. 2.4 and Lev. 18.5 as evidence of the human inability to do the law, in CD 3.12-17 and Pss. Sol. 14.1-2 we find that Lev. 18.5 is quoted to the effect that keeping the law is indeed possible for Israel.
