2 Samuel 20:26

The Jairite; so called from his birth or dwelling in the country of Jair in Gilead, Numbers 32:41 Judges 10:4. A chief ruler; either the president of the king's council; or his chief minister (as the Hebrew word cohen signifies) of state, instead of Ahithophel; or in some other very high place near the king's person. Compare 2 Samuel 8:18, where this title is given to David's sons, the chief of which were now cut off. And these things are here repeated with some alteration to show that David was now fully re-established in his former estate.
