Hushai
Easton's Dictionary
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.
International Standard Bible Encyclopedia
hut'-shi, hus'-sha-i (chushay, Chousei; Josephus, Chousi): An Archite, native of Archi or Erech(?), West of Bethel on the northern border of Benjamin and southern border of Joseph (Jos 16:2). Hushai was one of David's most faithful and wise counselors. When David was fleeing from Jerusalem and Absalom, Hushai met him, having his coat rent and earth on his head. The king persuaded him to return to Jerusalem, feign submission to Absalom, and try to defeat the counsel of Ahithophel (2Sa 15:32 f). Whatever Absalom decided on, Hushai was to send word to David through two young men, sons of the priests Zadok and Abiathar (2Sa 15:34-36). Hushai obeyed, and succeeded in persuading Absalom to adopt his counsel rather than that of Ahithophel (2Sa 16:16-17:14). He sent word to David of the nature of Ahithophel's counsel, and the king made good his escape that night across the Jordan. The result was the suicide of Ahithophel and the ultimate defeat and death of Absalom.
