I learned something very interesting yesterday at synagogue about the origins of the police.

I was reading a commentary on the weekly Torah portion, which I had written about (drawing attention to the theme of "justice" in the text). The commentary pointed out that while the emphasis in the Torah is on judges, it also mentions the importance of "law enforcement officials" in Deuteronomy 16:18: "You shall set up judges and law enforcement officials for yourself in all your cities that the Lord, your God, is giving you, for your tribes, and they shall judge the people [with] righteous judgment."

The commentary noted that while in the Messianic age, people would not need police officers to enforce the law, in todays age we do. (My rabbi noted that the Biblical ideal was to have "counselors," not police, to assist in the administration of justice, in the perfect world in which human beings never sought to flout the law.)

The relevance of Deuteronomy 16:18 was not lost on the congregants. We have been told for more than a year by the luminaries of Black Lives Matter -- in the streets, on cable news, and in the editorial pages -- that modern-day policing is a legacy of slavery, somehow tracing its origins to the officers who were dispatched to catch slaves that had escaped. It always came across as complete garbage, but it was spoken with great confidence and with an air of high dudgeon.

The reality: anyone who has a Bible can learn that police have existed for thousands of years. Moreover, the people Moses were addressing (or their parents) had just emerged from slavery themselves. The Bible recognizes that police are essential to the protection of freedom.

Think of Deuteronomy 16:18 the next time you encounter BLM.
