Do you observe all the other laws specified in Leviticus 19?
I’d be surprised if he didn’t, most of them are pretty common sense, though a few of the “coughing up a ram” type be somewhat outdated.
Additionally, they make sense, particularly at that time, even if regarded from a secular standpoint, because by not following those laws society pretty much rots away, or became easy pickings for more disciplined ones.
The “killy” OT rules are in 20...
Do you follow only the ones you feel like following?
I’m not a ‘Christian’.
