Josiah

Often ‘Yahweh supports’; exact derivation debated

Josiah is an English form of a Hebrew masculine name, often interpreted as ‘Yahweh supports’. The reference to God is clear, though the first part of the name has competing explanations, so the full meaning is not certain. Its biblical namesake is a king of Judah associated with religious reform. That gives Josiah a substantial scriptural setting. In English, the strong middle stress and unstressed final vowel create an expansive, lilting rhythm. It may appeal if you want the religious connection to be evident while the sound remains flowing rather than clipped.

Etymology: English form of Hebrew Yoshiyahu; the ending refers to Yahweh, while the first element is disputed.
