Ahithophel saw that his advice had not been followed, he put his house in order and then hanged himself.

 2 Samuel 17:15-29

Hushai told Zadok and Abiathar, the priests, “Ahithophel has advised Absalom and the elders of Israel to do such and such, but I have advised them to do so and so. Now send a message at once and tell David, ‘Do not spend the night at the fords in the wilderness; cross over without fail, or the king and all the people with him will be swallowed up.’”

When Ahithophel saw that his advice had not been followed, he saddled his donkey and set out for his house in his hometown. He put his house in order and then hanged himself. So he died and was buried in his father’s tomb.

When David came to Mahanaim, Shobi son of Nahash from Rabbah of the Ammonites, and Makir son of Ammiel from Lo Debar, and Barzillai the Gileadite from Rogelim brought bedding and bowls and articles of pottery. They also brought wheat and barley, flour and roasted grain, beans and lentils, honey and curds, sheep, and cheese from cows’ milk for David and his people to eat. For they said, “The people have become exhausted and hungry and thirsty in the wilderness.”

Why?

Ahithophel knew his advice had not been followed, David would return to Jerusalem, and he would be killed for he helped Ansalom, so he handed himself.

Barzillai did a great job when David's people were tired and hungry, he supported many food and roasted grain, honey, sheep and cheese, etc. It is important to those who escaped from Absalom the whole day.

How?

Help others at the needed point, pray at the right time, and say the key point during church service.
