Origin of the baby name Josiah

Josiah comes from the Biblical Hebrew name יֹאשִׁיָּה (Yoshiyahu), a compound of a root connected to the divine name Yahweh and a root meaning to support, heal, or let come to rest. The name passed through Greek as Iosias and then into Latin and English Bible translations, where it became familiar as the name of a beloved king of Judah. The longer Hebrew form יֹאשִׁיָּהוּ appears in some texts, reflecting a slightly fuller expression of the same meaning.
