God gave an interesting prophecy regarding Joseph (whose two sons, Ephraim and Manasseh, were adopted into Israel). He stated, "Joseph has the strength of a bull, the horns of a wild ox. His horns are Manasseh’s thousands and Ephraim’s ten thousands. With them he gores the nations and pushes them to the ends of the earth" (Deuteronomy 33:17).
The fact that Joseph (Israel) becomes Christianized while cast out of their land is the reason for the following prophecy. God states, through Isaiah, "Shake yourself from the dust; rise up! Sit, Jerusalem! Free yourself from your neckbands, O captive daughter of Zion, For thus says the LORD, "You were sold for nothing; and you shall be redeemed without money."" (Isaiah 52).
God also offers a prophecy that whoever attacks Israel will fall and that NO weapon will harm her. He also makes the incredible promise that HE will defend her and give her victory (Isaiah 54:15 - 17).
The hope of the regathering of Israel was very much on the mind of Jesus' disciples. In fact, just before he ascended into heaven they asked Christ 'Lord, will you at this time give the Kingdom back to Israel?' (Acts 1:6). Jesus' answer was that it was not for them to know the exact time this will occur but that they need concern themselves with receiving God's power in just a few days. Later, on Pentecost in 30 A.D., right after Jesus' disciples received the outpouring of God's holy spirit, the apostle Peter said, "God had made a vow that he would make one of David’s descendants a king, just as David was " (Acts 2:30).
King David did not expect Jesus to assume the throne until after his resurrection from the dead. Is Christ now on the throne of David? No, not yet. Prophecy states that he shall return to the earth a second time to take his place of rule on David's throne. At the present time he is at God's right hand "Him has God exalted by His right hand to be a Prince and Savior" (Acts 5:31).
Yes, Christ will come back and rule the earth through the throne of his physical ancestor, King David of Israel. It was toward this hope that the angel Gabriel told Mary the prophecy that she would give birth to a King whose Kingdom would never end (Luke 1:32 - 33)!
