Habakkuk 1:4

Since God had not intervened to stem the tide of evil, as He had threatened to do in the Mosaic Law, the Judeans were ignoring His law. They did not practice justice in their courts, the wicked dominated the righteous, and the powerful perverted justice. These conditions were common in Judah.

It is clear from the Lord’s reply that follows that others in the nation beside Habakkuk were praying these prayers and asking these questions. The prophet spoke for the godly remnant in Judah.
