Obadiah announces “the The Day of the Lord, in prophetic writing, is the day of judgment when God will intervene directly in world affairs. As described in Zephaniah, for instance, God will sweep everything away. In Matthew's gospel God is described as gathering the elect on the day... More,” which will be “against all the nations.” The nations, especially Edom, will be destroyed, and Israel will be restored.
Obadiah, like other prophets, announces a coming judgment day, “the day of the LORD,” when Israel’s enemies will be judged and Israel herself will be restored. (For similar passages about the Day of the Lord, see Isaiah, son of Amoz, who prophesied in Jerusalem, is included among the prophets of the eighth century B.C.E. (along with Amos, Hosea, and Micah)--preachers who boldly proclaimed God's word of judgment against the economic, social, and religious disorders of their time. More 13:6; A prophet during the Babylonian exile who saw visions of God's throne-chariot, new life to dry bones, and a new Temple. More 30:3; Joel 2:1, 11, 31; Prophet to the northern kingdom who condemned Israel's oppression of the poor, calling for justice to "roll down like waters." More 5:18, 20.) The basis for judgment will be the deeds of the nations, “As you have done, it shall be done to you; your deeds shall return on your own head.” Specifically, because Edom betrayed Judah was the name of Jacob's fourth son and one of the 12 tribes. More, Edom itself will be destroyed.
Verse 16 speaks of the Israelites having “drunk” on the Holy is a term that originally meant set apart for the worship or service of God. While the term may refer to people, objects, time, or places, holiness in Judaism and Christianity primarily denotes the realm of the divine More mountain, and then of the nations “drinking.” This verse is best understood in light of Prophet who condemned Judah's infidelity to God, warned of Babylonian conquest, and promised a new covenant More 25:15-29, where God gives Jeremiah the “cup of the wine of wrath” and makes all the nations drink from it. Judah has already drunk from the cup of wrath, as evidenced by the Babylonian exile. Now the cup will pass to the other nations.
The final part of the passage holds out hope not only for Judah but also for the long-lost The Northern Kingdom consisted of ten of the twelve tribes of Israel and lasted for 200 years until it was destroyed by Assyria in 721 B.C.E. In the northern kingdom the kings were evil. Prophets like Elijah and Amos railed against them and their evildoing. More of Israel. The “house of Jacob” (Judah) and the “house of Joseph” (Israel) will be restored and they will consume Edom as fire consumes straw. The prophet’s message of judgment and restoration is summarized in these few verses.
