The Lord himself will give you a sign:
The virgin will conceive and give birth to a son,
and will call him Immanuel.
For the vision is yet for an appointed time;
But at the end it will speak, and it will not lie.
Though it tarries, wait for it;
Because it will surely come,
It will not tarry.
Jesus is a Jew. His parents, his neighbors, his friends, the angel Gabriel, they all called him Yeshua.
"An angel of the Lord appeared to Yosef in a dream, saying, “Yosef, son of David, do not be afraid to take to you Mary your wife, for that which is conceived in her is of the Holy Spirit. And she will bring forth a Son, and you shall call His name Yeshua, for He will save His people from their sins.”
“I was watching in the night visions,
And behold, One like the Son of Man,
Coming with the clouds of heaven!
He came to the Ancient of Days,
And they brought Him near before Him.
Then to Him was given dominion and glory and a kingdom,
That all peoples, nations, and languages should serve Him.
His dominion is an everlasting dominion,
Which shall not pass away,
And His kingdom the one
Which shall not be destroyed."
Open to me the gates of righteousness;
I will go through them,
And I will praise the Lord.
This is the gate of the Lord,
Through which the righteous shall enter.
