Here is the Bible passage describing the great Image seen by Nebuchadnezzar, king of Babylon in Daniel chapter two:
Daniel 2:31 Thou, O king, sawest, and behold a great image. This great image, whose brightness was excellent, stood before thee; and the form thereof was terrible. 32 This image’s head was of fine gold, his breast and his arms of silver, his belly and his thighs of brass, 33 His legs of iron, his feet part of iron and part of clay. 34 Thou sawest till that a stone was cut out without hands, which smote the image upon his feet that were of iron and clay, and brake them to pieces. 35 Then was the iron, the clay, the brass, the silver, and the gold, broken to pieces together, and became like the chaff of the summer threshingfloors; and the wind carried them away, that no place was found for them: and the stone that smote the image became a great mountain, and filled the whole earth. 36 This is the dream; and we will tell the interpretation thereof before the king. 37 Thou, O king, art a king of kings: for the God of heaven hath given thee a kingdom, power, and strength, and glory. 38 And wheresoever the children of men dwell, the beasts of the field and the fowls of the heaven hath he given into thine hand, and hath made thee ruler over them all. Thou art this head of gold. 39 And after thee shall arise another kingdom inferior to thee, and another third kingdom of brass, which shall bear rule over all the earth. 40 And the fourth kingdom shall be strong as iron: forasmuch as iron breaketh in pieces and subdueth all things: and as iron that breaketh all these, shall it break in pieces and bruise. 41 And whereas thou sawest the feet and toes, part of potters’ clay, and part of iron, the kingdom shall be divided; but there shall be in it of the strength of the iron, forasmuch as thou sawest the iron mixed with miry clay. 42 And as the toes of the feet were part of iron, and part of clay, so the kingdom shall be partly strong, and partly broken. 43 And whereas thou sawest iron mixed with miry clay, they shall mingle themselves with the seed of men: but they shall not cleave one to another, even as iron is not mixed with clay. 44 And in the days of these kings shall the God of heaven set up a kingdom, which shall never be destroyed: and the kingdom shall not be left to other people, but it shall break in pieces and consume all these kingdoms, and it shall stand for ever. 45 Forasmuch as thou sawest that the stone was cut out of the mountain without hands, and that it brake in pieces the iron, the brass, the clay, the silver, and the gold; the great God hath made known to the king what shall come to pass hereafter: and the dream is certain, and the interpretation thereof sure.
The image represents four successive Empires impacting upon Jerusalem which span the time from the days of Daniel to the return of Jesus Christ to establish the kingdom of God on earth.
The golden head represents the Babylonian Empire.
The chest and arms of silver represent the Medo-Persian Empire
The belly and thighs of brass represent the Greek Empire
The legs of Iron represent the Roman Empire
The feet and toes of iron mixed with clay represents the state of the world between the demise of the Roman Empire and the return of Jesus Christ.
The Stone that hits the image and grinds it to powder represents Jesus Christ.
The Stone becoming a mountain that fills the earth represents the kingdom of God.
Jesus Christ is to rule this world in righteousness initially for 1000 years.
He will rule from Jerusalem.
Luke 1:32 He shall be great, and shall be called the Son of the Highest: and the Lord God shall give unto him the throne of his father David: 33 And he shall reign over the house of Jacob for ever; and of his kingdom there shall be no end.
Isaiah 2 will be fulfilled:
Isaiah 2:1 The word that Isaiah the son of Amoz saw concerning Judah and Jerusalem. 2 And it shall come to pass in the last days, that the mountain of the LORD’S house shall be established in the top of the mountains, and shall be exalted above the hills; and all nations shall flow unto it. 3 And many people shall go and say, Come ye, and let us go up to the mountain of the LORD, to the house of the God of Jacob; and he will teach us of his ways, and we will walk in his paths: for out of Zion shall go forth the law, and the word of the LORD from Jerusalem. 4 And he shall judge among the nations, and shall rebuke many people: and they shall beat their swords into plowshares, and their spears into pruninghooks: nation shall not lift up sword against nation, neither shall they learn war any more.
The visions subsequently given to Daniel give more detail concerning these empires.
These visions in Daniel are also a primer for understanding the book of Revelation.
