That is a part of the "Mystery of Iniquity". Satan had blinded the minds of the Jewish religious leaders so that no matter what Christ did, they were wilfully blind to their true Messiah. Indeed they viewed Him contemptuously, and asserted that His miracles were done by the power of Satan!How anyone could doubt Jesus is the Messiah is a mystery to me.
And after God brought judgment upon Israel for this wilful blindness, they still refused to accept the Lord Jesus Christ as their Lord and Savior. Thus they were judicially blinded by God. See Romans 11. Actually Romans 9-11 gives you the complete picture.
However, many Jews have also believed on Christ since then, but once again, Satan has worked among them so that they choose to isolate themselves from Gentile Christians, and call themselves "Messianics" instead of Christians. This is the trend of Messianic Jews, who also wish to cling to Moses while they believe on Jesus. But the epistle to the Hebrews is written for them to teach all that you cannot have both Moses and Christ.
