🔼The name Haggiah in the Bible
The name Haggiah occurs only once in the Bible, and that in a genealogy without further details (1 Chronicles 6:30). So we know that Haggiah existed but we don't know who he was, except that he was descendant of Levi, who was the ancestor of one of the twelve tribes of Israel.
Haggiah was the sixth generation after Merari, the third son of Levi. The priestly sub-tribe of Merari carried the framework of the tabernacle in the wandering years (Numbers 3:36-37). Later this family was assigned twelve cities (Joshua 21:7) and became important in the worship services in the pre-Temple period (1 Chronicles 6:31-47).
