Captain. Heb. shalish. Literally, “third.” Perhaps an officer of some importance (see on Ex. 14:7). In the case of Joram the shalish was evidently the king’s aide, spoken of as the “lord on whose hand the king leaned” (see on 2 Kings 7:2). When Jehu slew Joram, Bidkar, his shalish, was ordered to dispose of the body of the fallen king (ch. 9:24, 25).
Argob and Arieh. The meaning of these words is not clear. The names may be those of either men or places.
Fifty men. Probably members of the royal guard who conspired with Pekah against the life of Pekahiah.
