The name has been slowly rising in use, currently ranking 3,379th in 2023 with approximately 1 in 50,238 boys receiving it. It reached its peak popularity in 2023, and has been on an upward trajectory since 2003. Though it hasn't yet appeared in any state's top 1000, its biblical roots and melodic sound appeal to families seeking a distinctive yet traditional name.
