Galatians 3:10

3:10 For as many as are of the works of the law are under the curse: for it is written, Cursed [is] every one that continueth not in all things which are written in the book of the law to do them.

James 2:10-11

2:10 For whosoever shall keep the whole law, and yet offend in one [point], he is guilty of all. 2:11 For he that said, Do not commit adultery, said also, Do not kill. Now if thou commit no adultery, yet if thou kill, thou art become a transgressor of the law.
