I wish more Christians studied scripture in it's original language. I googled some information as to why Christians do not keep the laws of the five books of Moses. I came upon your web site which quoted a few verses from Jermiah. I am a orthodox Jew who lived in Israel. I speak, read, live and breathe Hebrew. Your translation of the verses is way off.
Given that the quotations come from translations of Hebrew done by experts in the field, a claim that all the experts are wrong is suspect. Then on top of this you make an assertion without giving evidence and somehow think people are going to accept your claim? You need to do better than that.
