Thematic Bible: David's friend

Ahithophel was counselor to the king; and Hushai the Archite was the king’s companion and friend.

When David came to the summit [of Olivet], where he worshiped God, behold, Hushai the Archite came to meet him with his coat rent and earth upon his head. David said to him, If you go with me, you will be a burden to me. But if you return to the city and say to Absalom, I will be your servant, O king; as I have been your father's servant in the past, so will I be your servant now, then you may defeat for me the counsel of Ahithophel. read more.
Will not Zadok and Abiathar the priests be with you? So whatever you hear from the king's house, just tell it to [them]. Behold, their two sons are there with them, Ahimaaz, Zadok's son and Jonathan, Abiathar's son; and by them send to me everything you hear. So Hushai, David's friend, returned, and Absalom also came into Jerusalem.

And when Hushai the Archite, David's friend, came to Absalom, Hushai said to [him], Long live the king! Long live the king! Absalom said to Hushai, Is this your kindness and loyalty to your friend? Why did you not go with your friend? Hushai said to Absalom, No, for whom the Lord and this people and all the men of Israel choose, his will I be, and with him I will remain. read more.
And again, whom should I serve? Should it not be his son? As I have served your father, so will I serve you.
