The answer is: Those without fins and scales

Deut 14:9

In Deuteronomy, the guidelines about which creatures are clean or unclean fairly reflect the cultural perceptions and practices of the ancient Israelites. In the diving depths of scripture, we see that creatures from the water must have both fins and scales to make the cut for lunch! It's an interesting distinction, as many freshwater fish like trout and salmon fit the bill, but slippery beings like eels and catfish do not.

You might be curious who was munching on eels back then. Generally, these laws were not practical choices for diet, but instead served to reinforce a community’s identity and set apart their lifestyle. The laws ushered in a clue of ancient wisdom regarding health, which takes us to the notion that animals without these attributes might violate other natural principles or harbor unwanted toxins.

Now, step back for a minute, and you've also got thematic reverberations in other cultures! For the ancient Egyptians, similar ideas about purity can help us rediscover how interwoven dietary laws shaped social and religious constructs across godly civilizations.

Moreover, in later texts, we see various interpretations of the idea that there's so much more at play than just adhering to external rules—it flourishes into a broader discussion on being spiritually attuned. Contemplating what it truly means to inherit a pure heart rather than just a pure plate opens a whole new world of connections. So, history and narrative come together in a delightful splash that enriches not just our knowledge of the dry ink, but also inspires how we experience life!
