Divrey Hayamim Alef 26:10 Meaning and Commentary

1 Chronicles 26:10

Also Hosah, of the children of Merari, had sons
Who was a fellow porter of Obededom's at the ark, ( 1 Chronicles 16:38 ) .

Simri the chief (for though he was not the firstborn, yet his father
made him the chief);
the firstborn being unfit for service, either through want of an intellectual capacity, or of strength of body, or through some defect or another; according to the Syriac version, he was dead; so some understand the words, he, the father, had no firstborn remaining or living.
