Nahum prophesied of God's wrath and complete destruction of Nineveh, the capital city of Assyria. Nahum's prophecy, like Jonah's, was exclusively against Nineveh and contains no prophecy relating to the Christian dispensation.
Habakkuk is concerned with several questions concerning the evil of the people of God. Iniquity and perverseness, violence and destruction, judgments and contention filled the land. The law, the statutes, judgments and commandments of the Mosaic covenant were violated without restraint.
Zephaniah wrote "the word of the Lord," even though it was against his own nation and fellow countrymen. The sins he pointed out were all truly present in Judah and the judgments he predicted all came to pass.
Haggai was the first of the post-exilic prophets. His main concern was that the temple be rebuilt and that the work begin immediately. All the recorded prophecies of Haggai were given within a period of four months.
Zechariah was a contemporary of Haggai, sharing in the mission of encouraging Zerubbabel, Joshua and the people to build the temple. Like so many of God's prophets and preachers Zechariah begins his inspired oracles by challenging his people to truly repent. God's call to repentance was linked with a promise of reconciliation.
