MILLIE:
You are right that the people you mention from the Old Testament like Moses and David were not docile or even poor (certainty David wasn't). And a sheep is definitely to be sheared and eaten!
You can't be docile and expect to survive in the world. You NEED to speak up and/or defend yourself, verbally at least.
However, certain Jehovah's Witnesses don't know how to speak up and they came into the religion this way. The mistake they make is that they think it's "alright" because the religion likes them this way. They confuse it with a "Christian personality". Meanwhile, they have issues in everyday life, couldn't hold a job, etc.
