Mentioned in the Bible by name

Hushai

And it came to pass, when David was come to the top of the hill, where God (Elohim) is usually worshipped, that Hoshai the Archite came to meet him with his cloak torn and earth on his head.

And Hushai, David's friend, came into the city at the same time that Absalom was entering Jerusalem.

And it came to pass, when Choshai the Arkite, David's friend, had come to Absalom, that Choshai said to Absalom, "Long live the king, long live the king."

And Absalom said to Hushai, "Is this your kindness (loving care – Hebr. chesed) toward your friend? Why did you not go with your friend?"

And Choshai said to Avshalom, "No, but the one whom the Lord (Yahweh) and this people and all the men of Israel have chosen, he shall be king, and with him I will be.

And Avshalom said, "Call, I pray thee, also Choshai the Arkite, and let us hear what he has to say."

When Choshai came to Avshalom, Avshalom spoke to him and said, "Here is what Achitofel has said [the advice he has given us]. Should we do according to his word or not? Speak."

So Choshai said to Absalom, "The advice that Ahithophel has given this time is not good."

And Choshaj said, "You know your father and his men, that they are mighty warriors (men in their prime, full of their own strength and power) and they are embittered in their souls (minds) like a bear robbed of her cubs in the field, and your father is a warrior and does not spend the night with the people.

And Hushai said to Zadok and to Abiathar, the priests, "This and this is Ahithophel's counsel to Absalom and to the elders of Israel, and this is my counsel to them.

Ahithophel was the king's counselor, and Hushai the Archite was the king's friend.
