Note: this is only the tip of the iceberg... you also cannot eat meat and dairy in the same meal, etc... it's kinda spread throughout different books of the bible... God wasn't very organized when he wrote all those books...
The Talmudic rabbis believed that the biblical text only forbade eating a mixture of milk and meat, but because the biblical regulation is triplicated they imposed three distinct regulations to represent it:
not cooking meat and milk together (regardless of whether the result was eaten)
not eating milk and meat together (regardless of whether it was cooked together)
not benefiting from the mixture in any other way
Why did God need to repeat this law 3 times? Wouldn't a perfect God write it perfectly the first time?
Since you're talking about people who haven't read the Bible, and you're talking about hypocrites, perhaps you could show us the verses that say we can't eat meat and milk together.
Unless you're a hypocrite doing the same thing you're accusing other people of doing.
Dude... what the fuck don't you understand? The Jews wrote the bible! It's called the HEBREW BIBLE
