31 Someone told David, saying, “Ahithophel is among the conspirators with Absalom.”
David said, “Yahweh, please turn the counsel of Ahithophel into foolishness.” 32 It happened that when David had come to the top of the ascent, where God was worshiped, behold, Hushai the Archite came to meet him with his coat torn, and earth on his head. 33 David said to him, “If you pass on with me, then you will be a burden to me; 34 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.’ 35 Don’t you have Zadok and Abiathar the priests there with you? Therefore it shall be, that whatever thing you shall hear out of the king’s house, you shall tell it to Zadok and Abiathar the priests. 36 Behold, they have there with them their two sons, Ahimaaz, Zadok’s son, and Jonathan, Abiathar’s son; and by them you shall send to me everything that you shall hear.” 37 So Hushai, David’s friend, came into the city; and Absalom came into Jerusalem.

(Read 2 Samuel 15:31-37)
David prays not against Ahithophel's person, but against his counsel. He prayed this, in firm belief that God has all hearts in his hand, and tongues also. But we must second our prayers with endeavours, and David did so, else we tempt God. But we do not find wisdom and simplicity so united in any mere man, that we can perceive nothing which needs forgiveness. Yet, when the Son of David was treated with all possible treachery and cruelty, his wisdom, meekness, candour, and patience, were perfect. Him let us follow, cleave to, and serve, in life and in death.
