Zephaniah is a distinctive and intriguing given name of Hebrew origin, meaning "Yahweh has concealed" or "Yahweh has treasured." This name appears in the Old Testament as the prophet Zephaniah, who lived during the reign of King Josiah in Judah. In its original form, Zephaniah is composed of two elements: "Zeph" meaning "hidden," and "iah" which signifies "Yahweh" or God. The name was quite uncommon among the ancient Hebrews but gained some popularity among Christians during the Protestant Reformation, as people sought to adopt biblical names for their children. Today, Zephaniah is still a relatively rare name, adding an air of uniqueness to those who bear it.
"Zephaniah saw a significant increase in popularity from 2006 onwards, with a notable peak of 28 births in 2016 and consistent high numbers since then."
