Galatians 3:10-14

3:10 For all who rely on doing the works of the law are under a curse, because it is written, “Cursed is everyone who does not keep on doing everything written in the book of the law.” 3:11 Now it is clear no one is justified before God by the law, because the righteous one will live by faith. 3:12 But the law is not based on faith, but the one who does the works of the law will live by them. 3:13 Christ redeemed us from the curse of the law by becoming a curse for us (because it is written, “Cursed is everyone who hangs on a tree”) 3:14 in order that in Christ Jesus the blessing of Abraham would come to the Gentiles, so that we could receive the promise of the Spirit by faith.

Galatians 3:19

3:19 Why then was the law given? It was added because of transgressions, until the arrival of the descendant to whom the promise had been made. It was administered through angels by an intermediary.
