The Book of Zephaniah, a book of the Hebrew Bible and the Christian Old Testament, was probably written in the late 7th century BC. The Hebrew name Zephaniah means “the Lord hides.” Zephaniah was a prophet who ministered to the people of Judah during the reign of King Josiah. His book contains a message of judgment on Judah for its idolatry, injustice, and oppression of the poor. Zephaniah also promises a remnant of faithful people who will be spared from judgment and enjoy God's blessing.
