'Star' in the Bible

"Where is he who is born King of the Jews? For we saw his star in the east, and have come to worship him."

Then Herod secretly called the wise men, and learned from them exactly what time the star appeared.

They, having heard the king, went their way; and behold, the star, which they saw in the east, went before them, until it came and stood over where the young child was.

When they saw the star, they rejoiced with exceedingly great joy.
