2nd Samuel 17:1 Moreover Ahithophel said unto Absalom, Let me now choose out twelve thousand men, and I will arise and pursue after David this night: 2 And I will come upon him while he is weary and weak handed, and will make him afraid: and all the people that are with him shall flee; and I will smite the king only:
[Patriarchs & Prophets pp 739] Ahithophel well knew that David's situation was far from hopeless. A large part of the nation were still true to him; he was surrounded by tried warriors, who were faithful to their king, and his army was commanded by able and experienced generals. Ahithophel knew that after the first burst of enthusiasm in favor of the new king, a reaction would come. Should the rebellion fail, Absalom might be able to secure a reconciliation with his father; then Ahithophel, as his chief counselor, would be held most guilty for the rebellion; upon him the heaviest punishment would fall.
To prevent Absalom from retracing his steps, Ahithophel counseled him to an act that in the eyes of the whole nation would make reconciliation impossible. With hellish cunning this wily and unprincipled statesman urged Absalom to add the crime of incest to that of rebellion. In the sight of all Israel he was to take to himself his father's concubines, according to the custom of oriental nations, thus declaring that he succeeded to his father's throne. And Absalom carried out the vile suggestion.
Thus was fulfilled the word of God to David by the prophet, “Behold, I will raise up evil against thee out of thine own house, and I will take thy wives before thine eyes, and give them unto thy neighbor.... For thou didst it secretly: but I will do this thing before all Israel, and before the sun.” 2 Samuel 12:11, 12. Not that God prompted these acts of wickedness, but because of David's sin He did not exercise His power to prevent them.
2nd Samuel 16:21 And Ahithophel said unto Absalom, Go in unto thy father's concubines, which he hath left to keep the house; and all Israel shall hear that thou art abhorred of thy father: then shall the hands of all that are with thee be strong. 22 So they spread Absalom a tent upon the top of the house; and Absalom went in unto his father's concubines in the sight of all Israel.
May The Lord add His blessing to the study of His word. God bless!
