The answer is: Josiah

Zep 1:1

Zephaniah, often overlooked in the rich tapestry of the Hebrew prophets, prophesied during the reign of King Josiah of Judah. One of the young kings, Josiah came to power at just eight years old and is best known for initiating sweeping religious reforms aimed at restoring worship in Jerusalem. Interestingly, he was a catalyst for spiritual awakening in a time when temple worship had fallen out of favor and pagan practices led the people astray.

In the backdrop of Zephaniah's ministry, when society was grappling with corruption and idolatry, Josiah held a pivotal role. His discovery of the Book of the Law (likely a version of Deuteronomy) during temple renovations became a pivotal moment in Judah's history. This unexpected finding ignited a nationwide revival, prompting unique legislative reforms and a return to covenant faithfulness.

Zephaniah's message of judgement is sandwiched between condensed snippets of hope and future restoration, echoing other prophetic voices. You will find significant resemblance to Joel, as both prophets tackle themes of coming judgement but also eyes toward redemption.

Have you ever noticed how many Biblical names serve dual purposes, sometimes function as namesakes or theme undertones? The meaning of Zephaniah, "The Lord has hidden," can be seen reflected in the layers of judgements he proclaims, hidden yet ultimately leading towards the light of hope through faithful repentance. Beauty and struggle become companions in God's narrative through His followers, evident across the pages well before and after Zephaniah’s prose. What rich literature to savor!
