Galatians 3:10-11

For all who rely on the works of the law are under a curse, as it is written: "Cursed is everyone who does not continue to do everything written in the Book of the Law." (Deuteronomy 27:26) Clearly no one who relies on the law is justified before God, because "the righteous will live by faith." (Habakkuk 2:4)

For all who rely on the works of the law 
Galatians 2:15-16  We who are Jews by birth and not sinful Gentiles know that a person is not justified by the works of the law, but by faith in Jesus Christ. So we, too, have put our faith in Christ Jesus that we may be justified by faith in Christ and not by the works of the law, because by the works of the law no one will be justified.

are under a curse 
Galatians 3:13  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." (Deuteronomy 21:23)
Romans 4:14-15  For if those who depend on the law are heirs, faith means nothing and the promise is worthless, because the law brings wrath. And where there is no law there is no transgression.
Romans 7:7-10  What shall we say, then? Is the law sinful? Certainly not! Nevertheless, I would not have known what sin was had it not been for the law. For I would not have known what coveting really was if the law had not said, "You shall not covet." (Exodus 20:17; Deuteronomy 5:2) But sin, seizing the opportunity afforded by the commandment, produced in me every kind of coveting. For apart from the law, sin was dead. Once I was alive apart from the law; but when the commandment came, sin sprang to life and I died. I found that the very commandment that was intended to bring life actually brought death.
1 Corinthians 15:56  For the sting of death is sin, and the power of sin is the law.

"Cursed is everyone who does not continue to do everything written in the Book of the Law" 
Jeremiah 11:3  "Tell them that this is what the LORD, the God of Israel, says: 'Cursed is the one who does not obey the terms of this covenant--...' "

Clearly no one who relies on the law is justified before God 
Romans 3:28  For we maintain that a person is justified by faith apart from the works of the law.

because "the righteous will live by faith" 
Hebrews 10:38  And, "But my righteous one will live by faith. And I take no pleasure in the one who shrinks back." (Habakkuk 2:4)
