Baaseiah was an ancestor of Asaph, the temple musician. The name is explained as possibly meaning “the Lord is bold,” though it may also represent a form meaning “the work of the Lord.”
Baaseiah appears in the genealogy of Asaph, who served as a musician. His biblical significance is therefore chiefly genealogical and connected with temple music.
The name has more than one proposed explanation in the supplied material. One possibility connects it with the Lord’s boldness; another treats it as a form of Maaseiah, “the work of the Lord.”
