Psalm 22: 19-31. 14: 1-7, 53: 1-6., 39: 1-13 These Psalms are about prayer, praise, man's wickedness and David crying out to God to guard his ways that he may not sin with his tongue.
It must have been a very hard road for David to travel knowing his own flesh and blood was against him and trying to take his crown from him. But as God says "Touch not my anointed" And here Absalom was not listening. He knew that his father was anointed by God. David must have been a broken hearted father.

2 Samuel 16: 1-23 David and Ziba who was Medphilosheth's servant and David asked him Where is your masters son? the king asked. His reply was He's staying in Jerusalem for he said, "Today, the house of Israel will restore my father's kingdom to me.

Absalom asks advise from Ahithophel in how to conquer king David. Ahithophel told him to sleep with his fathers concubines in the sight of all Israel and it will show that you have become repulsive to your father, everyone with you will be encouraged then Ahithophel also advised Absalom in order to pursue David is to gather 12,000 men and that night he will attack him while he is weak and it will cause him to panic and all the people with him will scatter and I will strike down only the king and bring all the people back to you.
So Absalom told Hushai the plans and Hushai said that was a bad idea as David was a warrior an experienced soldier. The king won't be sleeping with his men he will be hiding in one of the caves. so Hushai told Absalom to gather from Dan to Beersheba and that he must personally go into battle. Then we attack David wherever we find him. and so Absalom took Hushai's advise but in the mean time Hushai sent a message via the priests Sadok and Abiathar that they must send someone to tell David. So this they did by sending a girl to pass that information to Jonathan and Ahimaaz who were staying at En-rogel and they in return will pass that information to David but in the process of all this they were spotted by a young man who then informed Absalom. So the two men left quickly and came to the house of a man in Bahurim. He had a well in his courtyard and lowered them into it andhis wife put a cover over it and some straw. Absaloms servants came looking for them and asked the woman where Ahimaaz and Jonathan was and she told them they had passed by toward the water. when they had left the men climbed out the well and went informed king David. When Ahithophel realized that his advice had not been followed, he saddled his donkeys and when and set his affairs in order and hung himself and was buried in his father's tomb.
David had arrived at Manhanaim by the time Absalom crossed the Mordan with all the men of Israel.
