Behold, I have given unto you the commandments; therefore keep my commandments. And this is the law and the prophets: for they truly testified of me.

I have given you commandments. So keep my commandments. This is what the law and the prophets mean. They told the truth about me.

I’ve given you commandments—so keep them. This is the law and the prophets, for they truly testified of me.“
