Jesiah is a modern American spelling that blends Jesse, the Hebrew name usually explained as "gift", with Josiah, "Yahweh supports", the reforming boy king of Judah. Parents who like the biblical -iah ending of Isaiah and Josiah but want something less common have turned to it. Jesiah entered the US top 1000 in 2023, climbed to number 804 in 2024 and ranks number 865 among boys in 2025.
