Now, the book of Revelation is made up of this symbolic language. It is not, however, confined to this book alone. There are many instances of it to be found elsewhere in the sacred volume, and in many cases it is explained by inspiration itself, thus giving us a reliable key to the whole. Joseph's dream of the eleven sheaves that made obeisance to his sheaf was of this description (Gen. 37:7, 8), and his eleven brethren were angered, because its meaning was apparent--that they should be humbled before him. Also, his dream of the sun, the moon, and the eleven stars (verses 9, 10) was understood to signify the subjection of the entire family unto him, which was actually fulfilled after Joseph's exaltation in Egypt. The chief butler's dream of the vine with three branches bearing grapes, which he took and pressed into the king's cup, was interpretated by Joseph as signifying the butler's restoration in three days to his former position of cup-bearer to the king; while the chief baker's dream of the three baskets upon his head, out of which the birds ate, was interpretated as signifying his execution in the same length of time. Gen. 40. Pharaoh's dream of the seven fat kine and the seven lean kine, also of the seven full ears and the seven thin ears, signified seven years of plenty and seven years of famine. Gen. 41. Again, the four divisions of King Nebuchadnezzar's wonderful image was explained by Daniel as signifying four universal monarchies and the ten toes as signifying the ten minor kingdoms which grew out of the fourth; while the stone that was cut out of the mountain without human intervention he interpreted as signifying the divine kingdom of God. Dan. 2. The two-horned ram of Daniel's vision (chap. 8), according to the explanation of the angel, symbolized the Medo-Persian empire, its two horns signifying the two dynasties of allied kings that composed it. The he-goat signified the Greco-Macedonian empire; his great horn, its first mighty king; and the four horns that replaced the great one when broken represented four kings under whom the empire would eventually be divided into as many parts. In the Apocalypse itself we have a number of symbols divinely interpreted, "The seven stars are the angels of the seven churches." "The seven candle-sticks which thou sawest are the seven churches." "The ten horns which thou sawest are ten kings." "The waters which thou sawest ... are peoples, and multitudes, and nations, and tongues." "The woman which thou sawest is that great city which reigneth over the kings of the earth," etc. It will be seen that the great underlying principle or _law_ upon which symbolic language is based is ANALOGY. An object is chosen to represent not itself, but something of analagous character.
