http://www.biblegateway.com/passage/?book_id=73&chapter=6&version=50
First Seal: The Conqueror
1 Now I saw when the Lamb opened one of the seals;[a] and I heard one of the four living creatures saying with a voice like thunder, “Come and see.” 2 And I looked, and behold, a white horse. He who sat on it had a bow; and a crown was given to him, and he went out conquering and to conquer.

Second Seal: Conflict on Earth
3 When He opened the second seal, I heard the second living creature saying, “Come and see.”[b] 4 Another horse, fiery red, went out. And it was granted to the one who sat on it to take peace from the earth, and that people should kill one another; and there was given to him a great sword.

Third Seal: Scarcity on Earth
5 When He opened the third seal, I heard the third living creature say, “Come and see.” So I looked, and behold, a black horse, and he who sat on it had a pair of scales in his hand. 6 And I heard a voice in the midst of the four living creatures saying, “A quart[c] of wheat for a denarius,[d] and three quarts of barley for a denarius; and do not harm the oil and the wine.”

Fourth Seal: Widespread Death on Earth
7 When He opened the fourth seal, I heard the voice of the fourth living creature saying, “Come and see.” 8 So I looked, and behold, a pale horse. And the name of him who sat on it was Death, and Hades followed with him. And power was given to them over a fourth of the earth, to kill with sword, with hunger, with death, and by the beasts of the earth.

Fifth Seal: The Cry of the Martyrs
9 When He opened the fifth seal, I saw under the altar the souls of those who had been slain for the word of God and for the testimony which they held. 10 And they cried with a loud voice, saying, “How long, O Lord, holy and true, until You judge and avenge our blood on those who dwell on the earth?” 11 Then a white robe was given to each of them; and it was said to them that they should rest a little while longer, until both the number of their fellow servants and their brethren, who would be killed as they were, was completed.

Sixth Seal: Cosmic Disturbances
12 I looked when He opened the sixth seal, and behold,[e] there was a great earthquake; and the sun became black as sackcloth of hair, and the moon[f] became like blood. 13 And the stars of heaven fell to the earth, as a fig tree drops its late figs when it is shaken by a mighty wind. 14 Then the sky receded as a scroll when it is rolled up, and every mountain and island was moved out of its place. 15 And the kings of the earth, the great men, the rich men, the commanders,[g] the mighty men, every slave and every free man, hid themselves in the caves and in the rocks of the mountains, 16 and said to the mountains and rocks, “Fall on us and hide us from the face of Him who sits on the throne and from the wrath of the Lamb! 17 For the great day of His wrath has come, and who is able to stand?”

Commentaries
Chapter 6
Four sound them.
Christ, the Lamb, opens the first seal: observe what appeared. A rider on a white horse. By the going forth of this white horse, a time of peace, or the early progress of the Christian religion, seems to be intended; its going forth in purity, at the time when its heavenly Founder sent his apostles to teach all nations, adding, Lo! I am with you alway, even to the end of the world. The Divine religion goes out crowned, having the Divine favour resting upon it, armed spiritually
against its foes, and destined to be victorious in the end. On opening the second seal, a red horse appeared; this signifies desolating judgments. The sword of war and persecution is a dreadful judgment; it takes away peace from the earth, one of the greatest blessings; and men who should love one another, and help one another, are set upon killing one another. Such scenes also followed the pure age of early Christianity, when, neglectful of charity and the bond of peace, the Christian leaders, divided among themselves, appealed to the sword, and entangled themselves in guilt. On opening the third seal, a black horse appeared; a colour denoting mourning and woe, darkness and ignorance.

He that sat on it had a yoke in his hand. Attempts were made to put a yoke of superstitious observances on the disciples. As the stream of Christianity flowed further from its pure fountain, it became more and more corrupt. During the progress of this black horse, the necessaries of life should be at excessive prices, and the more costly things should not be hurt. According to prophetic language, these articles signified that food of religious knowledge, by which the souls of men are sustained unto everlasting life; such we are invited to buy, Isa 55:1. But when the dark clouds of ignorance and superstition, denoted by the black horse, spread over the Christian world, the knowledge and practice of true religion became scarce. When a people loathe their spiritual food, God may justly deprive them of their daily bread. The famine of bread is a terrible judgment; but the famine of the word is more so. Upon opening the fourth seal, another horse appeared, of a pale colour. The rider was Death, the king of terrors. The attendants, or followers of this king of terrors, hell, a state of eternal misery to all who die in their sins; and in times of general destruction, multitudes go down unprepared into the pit. The period of the fourth seal is one of great slaughter and devastation, destroying whatever may tend to make life happy, making ravages on the spiritual lives of men. Thus the mystery of iniquity was completed, and its power extended both over the lives and consciences of men. The exact times of these four seals cannot be ascertained, for the changes were gradual. God gave them power, that is, those instruments of his anger, or those judgments: all public calamities are at his command; they only go forth when God sends them, and no further than he permits. (Rev 6:9-11)
