Verse 17. - Is this thy kindness to thy friend? After carrying the king to Ayephim, on the banks of the Jordan, the narrator now turns back to Absalom, because David was to wait at the caravanserai for news from Jerusalem. And immediately on his arrival, Hushai hastens into Absalom's presence, loudly exclaiming, "Long live the king!" for such is the meaning of the Hebrew. The young man is surprised; for Hushai was David's friend and trusted confidant. Yet he does not suspect this sudden breaking of old ties, but, looking at the bright side only, sees in it a proof that his party was looked upon as sure of success, and David's cause as hopeless. He welcomes, therefore, so notable an adherent, and Hushai's pretences confirm his self-deceit; for he professes to regard Absalom as king, not by fraud and violence, but by the formal choice of both Jehovah and the people. On this assumption, obedience to the nation's choice became a religious duty, and Hushai's love to the father was a pledge of love to the son. We must not, however, condemn Absalom for too easy credulity. The nation was in his favour, and, had he acted with promptitude, David's cause would have been lost.

16:15-23 The wisest counsellors of that age were Ahithophel and Hushai: Absalom thinks himself sure of success, when he has both; on them he relies, and consults not the ark, though he had that with him. But miserable counsellors were they both. Hushai would never counsel him to do wisely. Ahithophel counselled him to do wickedly; and so did as effectually betray him, as he did, who was designedly false to him: for they that advise men to sin, certainly advise them to their hurt. After all, honesty is the best policy, and will be found so in the long run. Ahithophel gave wicked counsel to Absalom; to render himself so hateful to his father, that he would never be reconciled to him; this cursed policy was of the devil. How desperately wicked is the human heart!And Absalom said to Hushai, is this thy kindness to thy friend?.... Meaning to David; though he would not mention his name, nor his title, nor even the relation of a father he stood in to him, only speaks of him as Hushai's friend: Hushai had professed great friendship to David, and David had been a friend to Hushai, had raised him to great honour in making him a counsellor, and had bestowed many favours and benefits on him, as Absalom knew full well; and therefore, to try his integrity, he puts this question, not as displeased with him, but overjoyed that such a trusty friend of David, and a wise counsellor of his, had deserted him, and come over to him and his party; nor does he mean to charge him with ingratitude, which he could not do without reproaching himself; on whom it might be justly retorted, is this thy kindness to thy father that begot thee, and has always expressed such a strong affection for thee, as to rebel against him?

why wentest thou not with thy friend? with David, when he went out of Jerusalem; for Absalom knew not that Hushai had been with David, but thought he stayed behind at Jerusalem, when David fled, which made him less suspicious of him.
