Hushai was an Arkite and a close friend and advisor to David. He played a crucial role during Absalom's rebellion by pretending to support Absalom, while in reality working to undermine Ahithophel's counsel and save David.

Meeting David on the Mount of Olives
When David fled from Jerusalem during Absalom's rebellion, Hushai met him on the Mount of Olives with torn clothes and dust on his head as a sign of mourning.
34But if you return to the city and say to Absalom, 'I will be your servant, O king; as I was your father's servant in the past, so now I will be your servant,' then you can frustrate Ahithophel's counsel for me.
Ahithophel advised pursuing David immediately, but Hushai argued persuasively for a different strategy that gave David time to escape. Absalom followed Hushai's advice.
8Hushai went on, "You know your father and his men: they are warriors, and they are as fierce as a bear in the field robbed of her cubs. Your father is a man of war; he will not spend the night with the troops.
9Even now he is hiding in one of the ravines or somewhere else. If some of your men fall at the first attack, whoever hears of it will say, 'There has been a slaughter among the troops who follow Absalom.'
10Then even the bravest man, with a heart like the heart of a lion, will melt with fear, for all Israel knows that your father is a warrior and that those with him are men of valor.
11So this is my advice: Let all Israel, from Dan to Beersheba, be gathered to you, as numerous as the sand on the seashore, and go yourself into battle at their head.
12Then we will come upon him wherever he may be found, and we will settle on him as the dew settles on the ground. Neither he nor any of the men with him will be left alive—not one.
13And if he withdraws into a city, all Israel will bring ropes to that city, and we will drag it down into the valley until not even a pebble of it can be found."
14Absalom and all the men of Israel said, "The advice of Hushai the Archite is better than the advice of Ahithophel." For the LORD had ordained that Ahithophel's good counsel be frustrated, so that the LORD might bring disaster on Absalom.
After his advice was accepted, Hushai sent a message through the priests Zadok and Abiathar and their sons to David, so that he could cross the Jordan safely.
16Now send word quickly and tell David: 'Do not spend the night in the plains of the wilderness, but cross over at once, or the king and all the people with him will be swallowed up.'"
17Jonathan and Ahimaaz were waiting at En-rogel, and a servant girl would go and bring them word, and they would go and report to King David, for they could not risk being seen entering the city.
21After they had gone, the two climbed out of the well and went and reported to King David. They said to him, "Get up and cross the water quickly, for this is what Ahithophel has advised against you."
