2 Samuel 15:27; 2 Samuel 15:36

27 The king also said to Zadok the priest, “Do you understand? Go back to the city with my blessing. Take your son Ahimaaz with you, and also Abiathar’s son Jonathan. You and Abiathar return with your two sons.

36 Their two sons, Ahimaaz son of Zadok and Jonathan son of Abiathar, are there with them. Send them to me with anything you hear.”
