Keep the Whole Torah as Jacob exhorts:

Jacob 2:8. If you really fulfill the royal Torah according to the Scriptures, “You will love your neighbor as yourself,” (Leviticus 19:18) you do well: 9. but if you show partiality, you are working sin, being exposed as a transgressor under the Torah (Teaching). 10. For whoever would keep the whole Torah (Teaching) but would stumble in one thing, has become guilty of all. 11. For the One Who said, “Do not commit adultery,” also said, “Do not commit murder:” but if you do not commit adultery but do commit murder, you have become a transgressor of Torah (Teaching). 12. So you must continually speak, and so you must act as one going to be judged through the law of freedom. 13. For judgment without mercy is to be given for the one who does not do mercy: mercy, full of glad confidence, has no fear of judgment.
