Verse 20. -
Give counsel among you; Hebrew,
for you; but we have no way in English of expressing the force of this phrase. In Greek it is called the ethic dative, and is supposed to give character to the address, and indicate that those to whom the words are spoken have also an interest in the matter.
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!
Then said Absalom to Ahithophel,.... Having two such able counsellors as he and Hushai, he directs his speech to Ahithophel, as being his first and chief counsellor:
give counsel among you what we shall do; he orders them to form a counsel, consult among themselves what was proper to be now done at Jerusalem, whether it was right to stay here or pursue after David and his men. Absalom did not send to the high priest to ask counsel of God, by Urim and Thummim before the ark, but wholly confided in his privy council.
