Hushai
   quick, "the Archite," "the king's friend" (1 Chr. 27:33). When
   David fled from Jerusalem, on account of the rebellion of
   Absalom, and had reached the summit of Olivet, he there met
   Hushai, whom he sent back to Jerusalem for the purpose of
   counteracting the influence of Ahithophel, who had joined the
   ranks of Absalom (2 Sam. 15:32, 37; 16:16-18). It was by his
   advice that Absalom refrained from immediately pursuing after
   David. By this delay the cause of Absalom was ruined, for it
   gave David time to muster his forces.
   

Hushai, their haste; their sensuality; their silence
