And now it came to pass that Samuel...did prophesy. Behold, I give unto you a sign...then cometh the Son of God.
And behold, this will I give unto you for a sign at the time of his coming; for behold, there shall be great lights in heaven.
And behold, there shall a new star arise, such an one as ye never have beheld...and it shall come to pass that whosoever shall believe on the Son of God, the same shall have everlasting life. Helaman 14
Now when Jesus was born in Bethlehem of Judea in the days of Herod the king, behold, there came wise men from the east to Jerusalem, saying, Where is he that is born King of the Jews? for we have seen his star in the east, and are come to worship him. Matthew 2:1-2
