Indeed, after the kingdom of the ram comes the kingdom of the male goat. This shaggy goat is the king of Greece. This king rushes and advances into the world. He comes with great speed and conquers one country after another. This is what the words in Daniel 8:5 point to, he rushed west across the face of the whole earth without touching the ground.
This king is Alexander the Great who in the fourth century BC manages to establish a great empire in a rather short time. In order to do this, he has to defeat the Medo-Persian Empire. This happens when he and his army fight battles with the army of King Darius III Codomanus (†330 BC). Darius’ army meets a crushing defeat. The goat really throws the ram to the ground and the empire of the Medes and Persians is beyond saving. From Babylon, Alexander the Great goes on to rule his mighty empire, which in Daniel 7:6 is symbolized by a leopard with four wings of a bird. He dies in 323 BC when he is just 32 years old. His son, known to us as Alexander IV, is born after his death.
21 And the goat is the king of Greece. And the great horn between his eyes is the first king.
