James 2:11

9 But if you show favoritism, you sin and are convicted by the law as transgressors.

10 Whoever keeps the whole law but stumbles at just one point is guilty of breaking all of it.

For He who said, “Do not commit adultery,” also said, “Do not murder.” If you do not commit adultery, but do commit murder, you have become a lawbreaker.

12 Speak and act as those who are going to be judged by the law that gives freedom.

13 For judgment without mercy will be shown to anyone who has not been merciful. Mercy triumphs over judgment.

Do read the surrounding verses too, because the context often says more than a single verse.
