“Every human being should have equal opportunity no matter what the situation is.” This statement fits well with the most prevalent world view these days. This is a modern perspective that most people would agree with in principle. 

But in the scriptures, God was not concerned about equality. He was focused on giving preference for the vulnerable, weak, forgotten, and downtrodden. Especially in the Old Testament, you’ll find multiple situations where God is warning his people that this is the kind of behavior that he expected from them. 

Others may behave differently, But this was God’s expectation regarding his own people.
