31 And, behold, Cushi came; and Cushi said, Tidings,  my lord the king: for the Lord hath avenged thee this day of all them that rose up against thee.
31 Then the Cushite arrived and said, "My lord the king, hear the good news! The Lord has vindicated you today by delivering you from the hand of all who rose up against you."
31 And behold, the Cushite came, and the Cushite said, "Good news for my lord the king! For the Lord has delivered you this day from the hand of all who rose up against you."
31 Then the Cushite arrived and said, "Good news, my master and king! God has given victory today over all those who rebelled against you!"
31 Just then the Cushite came, and the Cushite said, "There is good news, my lord the king! For the Lord has avenged you this day of all those who rose against you."
31 Then the man from Ethiopia arrived and said, "I have good news for my lord the king. Today the Lord has rescued you from all those who rebelled against you."

Commentary on 2 Samuel 18:19-33
(Read 2 Samuel 18:19-33)
By directing David to give God thanks for his victory, Ahimaaz prepared him for the news of his son's death. The more our hearts are fixed and enlarged, in thanksgiving to God for our mercies, the better disposed we shall be to bear with patience the afflictions mixed with them. Some think David's wish arose from concern about Absalom's everlasting state; but he rather seems to have spoken without due thought. He is to be blamed for showing so great fondness for a graceless son. Also for quarrelling with Divine justice. And for opposing the justice of the nation, which, as king, he had to administer, and which ought to be preferred before natural affection. The best men are not always in a good frame; we are apt to over-grieve for what we over-loved. But while we learn from this example to watch and pray against sinful indulgence, or neglect of our children, may we not, in David, perceive a shadow of the Saviour's love, who wept over, prayed for, and even suffered death for mankind, though vile rebels and enemies.
