Here’s a prime of how a doctrine can be derived from translational misunderstanding in scripture.
"Say to the Israelites: 'Do not eat any of the fat of cattle, sheep or goats. Leviticus 7:23 NIV
Speak unto the children of Israel, saying, Ye shall eat no manner of fat, of ox, or of sheep, or of goat. Leviticus 7:23 KJV
Say to the children of Israel: The fat of a sheep, and of an ox, and of a goat you shall not eat. Leviticus 7:23 Douay-Rheims
Without proper study one would conclude that you can’t eat fat from this verse. Or at least that Levitical Laws once prohibited it. The Torah actually forbids the eating of chelev from sacrificed animals. Chelev is organ and intestinal fats. This is the best portion of the sacrifice, and you do not remove it from your offering.
