Daniel 2:1, 31-35 King Nebuchadnezzar's Troubling Dream

Now in the second year of the reign of Nebuchadnezzar, he had dreams; and his spirit was troubled and his sleep left him. Once summoned, Daniel replied to the king, "You, O king, were looking and behold, there was a single great statue; that statue, which was large and of extraordinary splendor, was standing in front of you, and its appearance was awesome. The head of the statue was made of fine gold, its breast and its arms of silver, its belly and its thighs of bronze, and its legs of iron, its feet partly of iron and partly of clay. You continued looking until a stone was cut out without hands and it struck the statue on its feet of iron and clay and crushed them. Then the iron, the clay, the bronze, the silver and the gold were crushed all at the same time and it became like chaff from the summer threshing floors; and the wind carried them away so that not a trace of them was found. But the stone that struck the statue became a great mountain and filled the whole earth.

The interpretation is that God was giving revelation which kingdoms would rule over Judah and the world before the return of Christ. This is referred to as the Times of the Gentiles. In this dream, the gold stands for the Babylonian Empire who dominated the world and Judah.
The breasts of silver refer to the Medo-Persian Empire who overthrows the Babylonian rule.
The iron and clay refer to the Roman Empire who were destroyed from within their nation.
Finally the belly and thighs of brone refer to the Greek rule through Alexander the Great.

Daily Prayer: Father, you reveal the beginning from the end, yet we still act as though we had no clue about the future. We are a very selfish lot and are hard to discipline. Wake up this sleeping world with new revelation. Grant us wisdom to live a skillful life before you so that when your son comes, we will be ready for his return. In your holy name I pray Amen.
