'Counsel' in the Bible

Someone told David, saying, "Ahithophel is among the conspirators with Absalom." David said, "Yahweh, please turn the counsel of Ahithophel into foolishness."

but if you return to the city, and tell Absalom, 'I will be your servant, O king. As I have been your father's servant in time past, so will I now be your servant; then will you defeat for me the counsel of Ahithophel.'

Then Absalom said to Ahithophel, "Give your counsel what we shall do."

The counsel of Ahithophel, which he gave in those days, was as if a man inquired at the oracle of God: so was all the counsel of Ahithophel both with David and with Absalom.

Hushai said to Absalom, "The counsel that Ahithophel has given this time is not good."

But I counsel that all Israel be gathered together to you, from Dan even to Beersheba, as the sand that is by the sea for multitude; and that you go to battle in your own person.

Absalom and all the men of Israel said, "The counsel of Hushai the Archite is better than the counsel of Ahithophel." For Yahweh had ordained to defeat the good counsel of Ahithophel, to the intent that Yahweh might bring evil on Absalom.

When Ahithophel saw that his counsel was not followed, he saddled his donkey, and arose, and went home, to his city, and set his house in order, and hanged himself; and he died, and was buried in the tomb of his father.

Then she spoke, saying, "They were used to say in old times, 'They shall surely ask counsel at Abel;' and so they settled it.
