the hope of a messiah

Throughout the Old Testament, the prophets preached the hope of a coming Messiah.  I think of Jeremiah when he talked about the "Righteous Branch" He mentions Israel's hope twice in his book:

Jer. 23:5     “Look, the days are coming”—this is the LORD’s declaration--
    “when I will raise up a Righteous Branch for David.
    He will reign wisely as king
    and administer justice and righteousness in the land.

Jer. 33:15     In those days and at that time
    I will cause a Righteous Branch
    to sprout up for David,
    and he will administer justice
    and righteousness in the land.
This righteous branch from David would have 4 Bible books written about Him. Praise God!
