Thou shalt not seethe a kid in his mother’s milk. (Deuteronomy 14:21 KJV)
First, a reminder of the kosher laws. Including a reminder that a rabbit chews its cud. Not! I can accept he Lord calling a bat a bird, since they didn’t have cladograms back then, but rabbits don’t have cud. Period. An omniscient god would get this right, but bronze age goatherds wouldn’t.
The rest of the chapters are the Lord reminding the Israelites to celebrate the high holidays properly. While there’s a lot of talk about helping the poor, and forgiving debts (of other Israelites), the jarring notes is that, if you own an Israeli slave, you must set him free in the seventh year. Slaves? When did we stop being allowed by the Lord to own slaves?
Next: Deuteronomy 17-20.
