1 Kings 1:38

So Zadok the priest, and Nathan the prophet, and Benaiah the
son of Jehoiada
The three men that David sent for on this occasion:

and the Cherethites and the Pelethites;
not the sanhedrim, as Ben Gersom, but David's guards, over whom Benaiah was: these

went down;
from Jerusalem;

and caused Solomon to ride upon King David's mule;
as he had ordered:

and brought him to Gihon;
or Siloah, as the Targum; hence the Jews say {e}, they do not anoint a king but at a fountain; but this is the only instance of it.
