2nd Samuel 17:6 And when Hushai was come to Absalom, Absalom spake unto him, saying, Ahithophel hath spoken after this manner: shall we do after his saying? if not; speak thou. 7 And Hushai said unto Absalom, The counsel that Ahithophel hath given is not good at this time.
[Patriarchs & Prophets pp 741] “And Absalom and all the men of Israel said, The counsel of Hushai the Archite is better than the counsel of Ahithophel.” But there was one who was not deceived—one who clearly foresaw the result of this fatal mistake of Absalom's. Ahithophel knew that the cause of the rebels was lost. And he knew that whatever might be the fate of the prince, there was no hope for the counselor who had instigated his greatest crimes. Ahithophel had encouraged Absalom in rebellion; he had counseled him to the most abominable wickedness, to the dishonor of his father.
He had advised the slaying of David and had planned its accomplishment; he had cut off the last possibility of his own reconciliation with the king; and now another was preferred before him, even by Absalom. Jealous, angry, and desperate, Ahithophel “gat him home to his house, to his city, and put his household in order, and hanged himself, and died.” Such was the result of the wisdom of one, who, with all his high endowments, did not make God his counselor. Satan allures men with flattering promises, but in the end it will be found by every soul, that the “wages of sin is death.” Romans 6:23.
Hushai, not certain that his counsel would be followed by the fickle king, lost no time in warning David to escape beyond Jordan without delay. To the priests, who were to forward it by their sons, Hushai sent the message: “Thus and thus did Ahithophel counsel Absalom and the elders of Israel; and thus and thus have I counseled. Now therefore ... lodge not this night in the plains of the wilderness, but speedily pass over; lest the king be swallowed up, and all the people that are with him.”
2nd Samuel 17:17 Now Jonathan and Ahimaaz stayed by Enrogel; for they might not be seen to come into the city: and a wench went and told them; and they went and told king David. 18 Nevertheless a lad saw them, and told Absalom: but they went both of them away quickly, and came to a man's house in Bahurim, which had a well in his court; whither they went down.
May God add His blessing to the study of His word. "Good night" and God bless!
