These three particular verses tie into one of the beautiful descriptions of our Lord. He is the morning star! "It is very meaningful that God uses a star to show both shepherds and the magi the way to the baby Jesus. In Matthew 2:2, the magi even ask, "Where is He who has been born King of the Jews? For we saw His star in the east and have come to worship Him." They knew the prophecies about the Messiah and took the star as a sign - THE sign - for them." - TeachingMom.com
Numbers 24:17, 19
I shall see him, but not now: I shall behold him, but not nigh: there shall come a Star out of Jacob, and a Sceptre shall rise out of Israel, and shall smite the corners of Moab, and destroy all the children of Sheth.
Out of Jacob shall come he that shall have dominion . . . (KJV)
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.
II Peter 1:19
And we have the word of the prophets made more certain, and you will do well to pay attention to it, as to a light shining in a dark place, until the day dawns and the morning star rises in your hearts. (NIV)
