1 Kings 1:8

8Yet truly, Zadok, the priest, and Benaiah, the son of Jehoiada, and Nathan, the prophet, and Shimei and Rei, and the mature men of the army of David were not with Adonijah.
1:8The word ‘robur’ can mean strong or robust, but it can also mean mature or experienced. So the veterans of the army, who were older and experienced in battle, were faithful to David, despite his decline in his ability to lead, because of old age. But perhaps the newer recruits were impetuous and supported the younger leader, Adonijah.(Conte)
