Question: At Shul, I heard repeatedly that the Jewish people were 4000 years old and I had always thought that it was over 5000 years. I know that this is 5765 so how could it only be 4000? Thank you
Answer: The world was created 5766 year ago. Abraham, son of Terach father of Isaac, AKA "the first Jew", was born 1948 years later. It is therefore a common saying that the Jews are around for almost 4000 years.
