“Oh, the depth of the riches and wisdom and knowledge of God!”
There are a number of prophecies and allusions to Christ the Messiah throughout the Old Testament.
Think about that. God, in His infinitely glorious wisdom, had wonderfully planned the salvation of all peoples through the person and work of Jesus Christ–the only Son of God, God in the flesh.

Below are a few of the Old Testament prophecies concerning the birth of Jesus Christ.
Worship as you read them.
 And he said, “Hear then, O house of David! Is it too little for you to weary men, that you weary my God also?  Therefore the Lord himself will give you a sign. Behold, the virgin shall conceive and bear a son, and shall call his name Immanuel. He shall eat curds and honey when he knows how to refuse the evil and choose the good.  For before the boy knows how to refuse the evil and choose the good, the land whose two kings you dread will be deserted.  The LORD will bring upon you and upon your people and upon your father’s house such days as have not come since the day that Ephraim departed from Judah–the king of Assyria.”
For to us a child is born, to us a son is given; and the government shall be upon his shoulder, and his name shall be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace.
 But you, O Bethlehem Ephrathah, who are too little to be among the clans of Judah, from you shall come forth for me one who is to be ruler in Israel, whose coming forth is from of old, from ancient days.  Therefore he shall give them up until the time when she who is in labor has given birth; then the rest of his brothers shall return to the people of Israel.  And he shall stand and shepherd his flock in the strength of the LORD, in the majesty of the name of the LORD his God. And they shall dwell secure, for now he shall be great to the ends of the earth.
