Just a couple of verses to consider:
Deuteronomy 13:6-10 KJV (I have in no way taken these verses out of context, or twisted them, acording to the bible, this is God's message to to the jews.)
If thy brother, the son of thy mother, or thy son, or thy daughter, or the wife of thy bosom, or thy friend, which [is] as thine own soul, entice thee secretly, saying, Let us go and serve other gods, which thou hast not known, thou, nor thy fathers;
[Namely], of the gods of the people which [are] round about you, nigh unto thee, or far off from thee, from the [one] end of the earth even unto the [other] end of the earth;
Thou shalt not consent unto him, nor hearken unto him; neither shall thine eye pity him, neither shalt thou spare, neither shalt thou conceal him:
But thou shalt surely kill him; thine hand shall be first upon him to put him to death, and afterwards the hand of all the people.
And thou shalt stone him with stones, that he die; because he hath sought to thrust thee away from the LORD thy God, which brought thee out of the land of Egypt, from the house of bondage.
Telling a jew to worship Jesus falls under the jurisdiction of this verse (even if it is correct to worship Jesus). So any jew that has heard this, or thinks the same way as this, is beaing very genouris in turning you away. Acording to the bible, he is simply supposed to kill you.
Go ahead and read for yourself
