Obadiah

“You should not gloat over your brother’s day on the day of his misfortune,
You should not rejoice over the people of Judah on the day of their perishing,
And you should not speak so arrogantly on the day of their distress.”

~Obadiah 12

Many Bible prophecies are directed toward the nation of Edom because they were distant relatives of the nations of Israel and Judah.
Edomites descended from Esau, the twin brother of Jacob (Israel). (Ge. 36:1; De. 2:4-6)
As such, God expected mutual respect between the Edomites and his people.
But this did not end up being the case; there was often war between both nations. (1 Sam. 14:47; 2 Sam. 8:13; 2 Ki. 14:7; Amos 1:11)
In this particular prophecy, Jehovah God warns the Edomites that when judgment came upon Jerusalem, they should not rejoice.
Nowadays, God’s servants do not war against others, but try to bring people a message of peace and hope. (Matt. 24:14)
Sometimes we are in situations where people who used to be friendly/receptive to God’s message are suddenly and inexplicably rude to us.
We should not rush to judge those people, saying they deserve whatever judgment may be coming their way, nor rejoice in the idea of their future calamity.

Ezekiel, chapters 24-27

“I will take vengeance on Edom by the hand of my people Israel.”
~Ezekiel 25:14

Since most of Ezekiel’s prophecies were executed by Babylon’s army, how was this prophecy fulfilled?
Despite also being descendants of Abraham through Isaac, the people of Edom had demonstrated hatred toward the people of Israel throughout their history. (Ps. 137:7; Am. 1:11)
When Babylonian King Nebuchadnezzar destroyed Jerusalem and took the Jews captive, Edom was apparently an ally of Babylon. (Obad. 1, 7)
Some fifty years later, though, under the new Babylonian King Nabonidus, an army that included Jewish soldiers conquered Edom, thereby fulfilling the aforementioned prophecy. (Insight on the Scriptures, Vol. I. “Edom: Later History and Disappearance.”)
Edom did not survive as a nation. (Obad. 10)
How awe-inspiring it is to see Jehovah’s prophetic justice fulfilled.
