In the New Testament, Matthew 2:1-12 says,
Now when Jesus was born in Bethlehem of Judea in the days of Herod the king, behold, wise men from the East came to Jerusalem, saying, “Where is he who has been born king of the Jews? For we have seen his star in the East, and have come to worship him.” When Herod the king heard this, he was troubled, and all Jerusalem with him; and assembling all the chief priests and scribes of the people, he inquired of them where the Christ was to be born. They told him, “In Bethlehem of Judea; for so it is written by the prophet:
‘And you, O Bethlehem, in the land of Judah, are by no means least among the rulers of Judah; for from you shall come a ruler who will govern my people Israel.’”
Then Herod summoned the wise men secretly and ascertained from them what time the star appeared; and he sent them to Bethlehem, saying, “Go and search diligently for the child, and when you have found him bring me word, that I too may come and worship him.” When they had heard the king they went their way; and lo, the star which they had seen in the East went before them, till it came to rest over the place where the child was. When they saw the star, they rejoiced exceedingly with great joy; and going into the house they saw the child with Mary his mother, and they fell down and worshiped him. Then, opening their treasures, they offered him gifts, gold and frankincense and myrrh. And being warned in a dream not to return to Herod, they departed to their own country by another way.
There are also Old Testament prophecies concerning the Epiphany.
Isaiah 60:6 says, “A multitude of camels shall cover you, the young camels of Midian and Ephah; all those from Sheba shall come. They shall bring gold and frankincense, and shall proclaim the praise of the LORD.”
And in the Psalms,
Psalm 72:10–11 says, “May the kings of Tarshish and of the isles render him tribute, may the kings of Sheba and Seba bring gifts! May all kings fall down before him, all nations serve him!”
