'Counsel' in the Bible

Now David [was] told, "Ahithophel [was] among the conspirators with Absalom." Then David said, "Please frustrate the counsel of Ahithophel, O Yahweh."

but if you want to return to the city and say to Absalom, 'I [am] your servant, O king. I used to be a servant of your father, but from then and now I [will be] your servant,' then you can frustrate the counsel of Ahithophel for me.

The counsel that Ahithophel gave in those days [was] regarded as when a man inquired of the word of God, so all the counsel of Ahithophel [was esteemed] both by David and by Absalom.

Then Hushai said to Absalom, "The counsel that Ahithophel gave [is] not good {at this time}."

Then Absalom and all the men of Israel said, "The advice of Hushai the Arkite [is] better than the advice of Ahithophel." (Now Yahweh had ordained to frustrate the good counsel of Ahithophel in order for Yahweh to bring misery upon Absalom).
