2-я Царств 18:21

Joab therefore entrusted the Cushite with the duty of conveying to David the announcement of what had occurred. It cannot be decided with certainty whether הכּוּשׁי or Cushi is the proper name of an Israelite, or whether it signifies the "Cushite," i.e., a descendant of Cush. The form of the name rather favours the latter view, in which case it would suggest the idea of a Moorish slave in the service of Joab.

This chapter puts a period to Absalom's rebellion and life, and so makes way for David to his throne again, whither the next chapter brings him back in peace and triumph. We have here, I. David's preparations to engage the rebels (Sa2 18:1-5). II. The total defeat of Absalom's party and their dispersion (Sa2 18:6-8). III. The death of Absalom, and his burial (Sa2 18:9-18). IV. The bringing of the tidings to David, who tarried at Mahanaim (Sa2 18:19-32). V. His bitter lamentation for Absalom (Sa2 18:33).

18:21 a man from Ethiopia: Joab thought it would be better to send a foreigner to tell the king of Absalom’s death. If David overreacted, the loss of a foreigner was not as critical as the loss of a priest’s son.
