How you have fallen from heaven, morning star

Isaiah 14:1-20
The Lord will have compassion on Jacob; once again he will choose Israel and will settle them in their own land. Foreigners will join them and unite with the descendants of Jacob.
On the day the Lord gives you relief from your suffering and turmoiland from the harsh labor forced on you,  you will take up this tauntagainst the king of Babylon : How the oppressor has come to an end! How his fury has ended!
You also have become weak, as we are; you have become like us.
How you have fallen from heaven, morning star, son of the dawn! You have been cast down to the earth, you who once laid low the nations!
You will not join them in burial, for you have destroyed your land and killed your people. Let the offspring of the wicked never be mentioned again.
In Isiah's day Babylon was struggling for independence from Assyria. This prophecy concerns Babylon, 100 year later, at the height of it power - and looks forward to the day when Babylon in turn will be brought down.
In 539 Babylon fell to the Medes and Persians led by Cyrus. Xerxes destroyed the city in 478, and it was finally abandoned in the 4th century BC. In the New Testament, Babylon becomes a symbol. It is the city of rebel humanity, implacably(無情) opposed to God.
Why?
Human proud and their kingdom, authority will goes away and fell down one day. All become realm of the dead below. What the value of a man in the world?
The Lord have compassion on Jacob and to those who follow his word. God give us relief from suffering and turmoil and from the harsh labor forced on us.
Do not envy or angry to the evil doers, only those who walking on the way of the Lord and trust in Jesus Christ have eternal life.
How?
How you have fallen from heaven, morning star. Be humble and obey God's word and do what God's delight things.
