I like Rabbi Joseph Bekhor Shor's interpretation. It's far from being accepted in Judaism - probably because it makes so much sense.

The interpretation is based on the fact that the passage originally appears in Exodus twice - but not in a section about Kosher laws. It appears in sections about Bikurim - bringing offerings to the temple:

• https://www.biblegateway.com/passage/?search=Exodus+23%3A14-19&version=CSB
• https://www.biblegateway.com/passage/?search=Exodus+34%3A22-26&version=CSB

The very same verse that contains that law also contains a law about Bikkurim:

Bring the best firstfruits of your land to the house of the Lord your God.

You must not boil a young goat in its mother’s milk.

Because these two laws seem so unrelated, Rabbi Joseph Bekhor Shor suggests a different way to read the second part.

In Hebrew, the root of the word "cook"/"boil" is B-SH-L - and this is also the root of the word "ripe"/"mature". Because of that, it's possible to read "you must not boil a young goat in its mother’s milk" as "you must not let a young goat mature while drinking its mother's milk".

This makes the second part of the verse a repetition of the first part - a pattern very common in the Old Testament as a (vain) attempt to prevent misinterpretations. Reading it like so, both parts mean "the offerings should be as young and as fresh as possible".

That reading is a little bit odd - but not too odd in biblical language standards, and it makes so much more sense in the context where the passage appears.

This would have come from a time when ancient Judaism was evolving out of its polytheistic roots. The early sections of the Hebrew scriptures tended to treat other gods as existing, but you're only supposed to worship YHWH.

Likely, there was some specific ritual that had been used in local polytheistic practices, and it's specifically telling you not to do that.

This is an issue for the sort of fundamentalists who insist that absolutely everything in the bible is useful for modern times. You say that, but then what's this goat milk thing about? How about all the idolatry prohibitions when many modern Christians won't regularly encounter religions that use idols? Why is there a whole book devoted to Solomon's horny poetry?

You can kinda come up with answers to those, but they will invariably involve some kind of "reading between the lines". That is, reading assumptions into the text that aren't explicitly stated. Which fundamentalists also say you're not supposed to do.

opposite idea from mixing powdered milknin fresh milk for "more milk per milk."

I mean I do feel weird whenever I do this. The solution is soy milk!

I'm conceptually opposed to oat milk generally.

Wow yea that sounds pretty sociopathic

It's why I refuse to eat chicken and eggs

Deuteronomy is originally from the Hebrew Bible. According to Jewish mythology, the book is from the sermons of Moses. Though, it's believed to be much more recent (something like a 1000 years) than the time period where the figure of Moses (or the person(s) he was based on) would have existed. But, even taking Jewish and Christian mythologies at their word, Jesus had nothing to do with that rule. Also, Jesus probably meant for this rule to end for adherents of Christianity.

Mark 7:14-23:
14 Again Jesus called the crowd to him and said, “Listen to me, everyone, and understand this.
15 Nothing outside a person can defile them by going into them. Rather, it is what comes out of a person that defiles them.”
17 After he had left the crowd and entered the house, his disciples asked him about this parable.
18 “Are you so dull?” he asked. “Don’t you see that nothing that enters a person from the outside can defile them?
19 For it doesn’t go into their heart but into their stomach, and then out of the body.” (In saying this, Jesus declared all foods clean.)
20 He went on: “What comes out of a person is what defiles them.
21 For it is from within, out of a person’s heart, that evil thoughts come—sexual immorality, theft, murder,
22 adultery, greed, malice, deceit, lewdness, envy, slander, arrogance and folly.
23 All these evils come from inside and defile a person.”

So, feel free to boil a young goat in its mother's milk. Jesus is A-ok with that.

As much as I appreciate Japanese culture, they also created Oyakodon, which literally means "parent-and-child rice bowl". Like damn, Japan, what'd those birds ever do to you to necessitate multi-generational violence?

Then you extrapolate that and the only way to stay kosher is to never prepare meat with dairy. No philly cheese steak, no butter.

More oats per oats

I have dairy in my diet, but when it comes to porridge, oat milk only please

Jesus was born 5-7 centuries after this was written down, he don't know either.

One of my colleague like to have roasted potato with vegan mayo. So he is having potatoes cooked in oil together with potatos emulsified with oil.

Reminds me of the milk rice I made with rice milk. Not a good idea. I generally don't like rice milk so that might be why. Muesli with oat milk is fine
