The Hebrew proper name Nowbay (Nobai) refers to an Israelite leader who sealed the covenant with Nehemiah after the return from exile. The name likely derives from the root nuwb meaning "fruitful," suggesting a name meaning "my fruit" or "productive one."
Nobai appears in the list of leaders who set their seal on the renewed covenant in the time of Nehemiah. This act of covenant renewal was a pivotal moment in Israel's post-exilic restoration, representing the community's recommitment to the Torah after decades of exile. Each signatory testified to God's faithfulness in bringing His people back to the land.
