“You have heard it said……But I say to you….” Jesus, Sermon on the Mount.
When Jesus gets into the meat of his sermon on the mount, with the very practical applications, he starts many of his paragraphs with “you have heard it said.” When he says this, he’s referring to the Bible. The Bible says this, but I say this. Jesus doesn’t contradict the Bible, but he does interpret it. The Bible says don’t commit adultery. Jesus says don’t even look at someone with lust in your heart. Jesus expects more from his followers than just obedience to the Bible. We are to be obedient to Jesus. Jesus is the one who will tell us what the Bible means, not just what it says.
