So says Jehovah of Hosts, Do not listen to the words of the prophets who prophesy to you. They make you vain; they speak a vision from their own heart, not out of the mouth of Jehovah.
Then purposing this, did I indeed use lightness? Or the things that I purpose, do I purpose them according to the flesh, so that with me there should be yes, yes, and no, no?
You shall not add to the Word which I command you, neither shall you take away from it, so that you may keep the commands of Jehovah your God which I command you.
