And the sons of Jerahmeel, the firstborn of Hezron, were Ram
the firstborn
So called by his father after the name of his brother, see ( 1 Chronicles 2:9 )
and Bunah, and Oren, and Ozem, and Ahijah;
or "of Ahijah", as some F18 render it, this being the name of his wife, who bare him the sons before named, since mention is made of another wife in the next verse.
