Obidiah is a variant of Obadiah, the Hebrew biblical name meaning servant of the Lord.
Obidiah is an orthographic variant of Obadiah, a name rooted in the Hebrew עֹבַדְיָה (Ovadyah), meaning "servant of Yahweh" or "worshipper of God." The root combines eved (servant) with the divine name, placing it in a rich family of Hebrew theophoric names that express devotion through identity itself. Obadiah appears in the Hebrew Bible as one of the twelve minor prophets, author of the shortest book in the Old Testament — a fierce, compact vision concerning the fate of Edom.
The name also belongs to a steward of King Ahab who sheltered a hundred prophets from Jezebel's purges, a figure of quiet courage hidden inside palace walls. The name found wide favor among the Puritans of seventeenth-century England and colonial New England, who combed scripture for names that announced theological conviction. That heritage gave Obidiah a distinctly austere, Old World gravity, and it fell into deep obscurity as secular naming fashions took hold through the eighteenth and nineteenth centuries.
The -diah ending, shared with Jedidiah and Zebediah, carries a particular resonance — sonorous and archaic at once. Today Obidiah occupies that rare category of names that feel simultaneously ancient and fresh. Its uncommonness is itself a draw for parents seeking something rooted in tradition without the ubiquity of more popular biblical names.
The spelling with an i rather than an a gives it a slightly modernized silhouette while preserving every syllable of its prophetic ancestry. Nicknames Obie and Obi bring it gently into the present.
