This is that Benaiah, who was mighty among the thirty. — Literally, he, Benaiah, was a hero of the thirty. (Comp. 1 Chronicles 11:25; 2 Samuel 23:23.)
And in his course. — Heb., and his course. Ammizabad his son. Comp. the second clause of 1 Chronicles 27:4. Here, as there, the LXX. and Vulg. give the sense “over his course,” as if Ammizabad were coadjutor with his father. The text may be defective in both places.
