“Parteth the hoof”, AND “is clovenfooted” AND “cheweth the cud” = OK to eat.
Supper had to meet ALL THREE of these requirements because of the “AND” words. God gave the people an example of an animal that DID NOT meet all three characteristics as He talked about swine in verse 7:
And the swine, though he divide the hoof, and be clovenfooted, yet he cheweth not the cud; he is unclean to you.
Divided hoof AND is clovenfooted NOT cheweth the cud = DO NOT eat.
In the verse, you could be fancy and replace the “AND”s and “NOT”s with plusses and minuses.
+Divided hoof +clovenfooted –cheweth cud = do not eat.
When searching the web for things, the same kind of advanced selecting is being used, as in Leviticus 11. You’re selecting hits from over a TRILLION webpages based on detailed characteristics. You want web pages (called ‘hits’) that have this AND this AND this but NOT that.
