God used a pagan prophet to speak truth to Israel. The prophet was Balaam and the truth was about the coming Messiah.
The oracle of Balaam the son of Beor, and the oracle of the man whose eye is opened, the oracle of him who hears the words of God, and knows the knowledge of the Most High, who sees the vision of the Almighty, falling down, yet having his eyes uncovered. I see him, but not now; I behold him, but not near; a star shall come forth from Jacob, a scepter shall rise from Israel, and shall crush through the head of Moab, and tear down all the sons of Sheth. Numbers 24: 15 – 17
The star of Jacob is a Messianic theme, alluded to by Isaiah when he spoke of the Messiah:
The people who walk in darkness will see a great light; those who live in a dark land, the light will shine on them. Isaiah 9: 2
John continued this theme of light:
The Light shines in the darkness, and the darkness did not comprehend it. John 1: 5
Jesus Himself said this:
I, Jesus, have sent My angel to testify to you these things for the churches. I am the root and the descendant of David, the bright morning star. Revelation 22: 16
Given these Scriptures considered, one might say that on the very first Christmas, in the Bethlehem manger, a star was born.
