Charles Spurgeon Commentary 2 Samuel 15:33-37

"And David said unto him, If thou passest on with me, then thou wilt be a burden unto me: but if thou return to the city, and say unto Absalom, I will be thy servant, O king; as I have been thy father`s servant in time past, so will I now be thy servant; then wilt thou defeat for me the counsel of Ahithophel. And hast thou not there with thee Zadok and Abiathar the priests? therefore it shall be, that what thing soever thou shalt hear out of the king`s house, thou shalt tell it to Zadok and Abiathar the priests. Behold, they have there with them their two sons, Ahimaaz, Zadok`s son, and Jonathan, Abiathar`s son; and by them ye shall send unto me everything that ye shall hear. So Hushai, David`s friend, came into the city; and Absalom came into Jerusalem." — 2 Samuel 15:33-37 (ASV)

You know the rest of the history, how Absalom took the advice of Hushai, and Ahithophel was defeated. God does not always answer prayer quite as rapidly as he did in this case. Yet, when his people are in dire straits, they often receive prompt replies to their petitions, to encourage their faith, and to keep their hope alive in the time of trial.
