Delivers will go up on Mount Zion to govern the mountains of Esau; Obadiah

Obadiah 1-21
This is what the Sovereign Lord says about Edom.
See, I will make you small among the nations; you will be utterly despised. The pride of your heart has deceived you, you who live in the clefts of the rocks and make your home on the heights, you who say to yourself, 'Who can bring me down to the ground' Though you soar like the eagle and make your nest among the stars, from there I will bring you down," declares the Lord.
Because of the violence against your brother Jacob, you will be covered with shame; you will be destroyed forever.
The day of the Lord is near for all nations. As you have done, it will be done to you;  your deeds will return upon your own head.
People from the Negev will occupy the mountains of Esau, and people from the foothills will possess the land of the Philistines. They will occupy the fields of Ephraim and Samaria and Benjamin will possess Gilead.
Delivers will go up on Mount Zion to govern the mountains of Esau. And the kingdom will be the Lord's.
Nothing but his name is known of this prophet. His prophecy concerns the downfall of Edom.
Edom occupied the mountainous region south-east of the Dead Sea. The capital Sela was perched high on a plateau above a sheer rick cliff approached by a narrow gorge. It was virtually impregnable. From mountain strongholds like this the Edomites launched their raids on Palestine. As Esau's descendants they were in fact kin to Israel, but there was never any love lost between the two. The final outrage - and the occasion of Obadiah's prophecy - was their invasion of Judah while Jerusalem was being sacked by the Babylonians in 587BC.
Obadiah denounces Edom's pride. The Edomistes though their strongholds invincible, but they would be utterly destroyed.
Why?
Edom was pride and proud for his strongholds. Edom did not love his brothers, so the destroy came upon them.
God declares that delivers will go up on Mount Zion to govern the mountains of Esau. And the kingdom will be the Lord's. God is the sovereign Lord forever.
Deliver will go up on Mount Zion, the savior, Jesus Christ will be ruler on Easu and all the world.
Your deeds will return upon your own head, God is judge and He is fair to everyone, what you deeds will return upon your own head.
How?
Be a faithful Christian to the Lord! Rejoice and fear the Lord, God is my real stronghold.
