Here is, I. The great respect David paid to his neighbour, the king of the Ammonites, Sa2 10:1, Sa2 10:2. 1. The inducement to it was some kindness he had formerly received from Nahash the deceased king. He showed kindness to me, says David (Sa2 10:2), and therefore (having lately had satisfaction in showing kindness to Mephibosheth for his father's sake) he resolves to show kindness to his son, and to keep up a friendly correspondence with him. Thus the pleasure of doing one kind and generous action should excite us to another. Nahash had been an enemy to Israel, a cruel enemy (Sa1 11:2), and yet had shown kindness to David, perhaps only in contradiction to Saul, who was unkind to him: however, if David receives kindness, he is not nice in examining the grounds and principles of it, but resolves gratefully to return it. If a Pharisee give alms in pride, though God will not reward him, yet he that receives the alms ought to return thanks for it. God knows the heart, but we do not. 2. The particular instance of respect was sending an embassy to condole with him on his father's death, as is common among princes in alliance with each other: David sent to comfort him. Note, It is a comfort to children, when their parents are dead, to find that their parents' friends are theirs, and that they intend to keep up an acquaintance with them. It is a comfort to mourners to find that there are those who mourn with them, are sensible of their loss and share with them in it. It is a comfort to those who are honouring the memory of their deceased relations to find there are others who likewise honour it and who had a value for those whom they valued.

II.The great affront which Hanun the king of the Ammonites put upon David in his ambassadors. 1. He hearkened to the spiteful suggestions of his princes, who insinuated that David's ambassadors, under pretence of being comforters, were sent as spies, Sa2 10:3. False men are ready to think others as false as themselves; and those that bear ill-will to their neighbours are resolved not to believe that their neighbours bear any good-will to them. They would not thus have imagined that David dissembled but that they were conscious to themselves that they could have dissembled, to serve a turn. Unfounded suspicion argues a wicked mind. Bishop Patrick's note on this is that "there is nothing so well meant but it may be ill interpreted, and is wont to be so by men who love nobody but themselves." Men of the greatest honour and virtue must not think it strange if they be thus misrepresented. Charity thinketh no evil. 2. Entertaining this vile suggestion, he basely abused David's ambassadors, like a man of a sordid villainous spirit, that was fitter to rake a kennel than to wear a crown. If he had any reason to suspect that David's messengers came on a bad design, he would have done prudently enough to be upon the reserve with them, and to dismiss them as soon as he could; but it is plain he only sought an occasion to put the utmost disgrace he could upon them, out of an antipathy to their king and their country. They were themselves men of honour, and much more so as they represented the prince that sent them; they and their reputation were under the special protection of the law of nations; they put a confidence in the Ammonites, and came among them unarmed; yet Hanun used them like rogues and vagabonds, and worse, shaved off the one half of their beards, and cut off their garments in the midst, to expose them to the contempt and ridicule of his servants, that they might make sport with them and that these men might seem vile.

III.David's tender concern for his servants that were thus abused. He sent to meet them, and to let them know how much he interested himself in their quarrel and how soon he would avenge it, and directed them to stay at Jericho, a private place, where they would not have occasion to come into company, till that half of their beards which was shaved off had grown to such a length that the other half might be decently cut to it, Sa2 10:5. The Jews wore their beards long, reckoning it an honour to appear aged and grave; and therefore it was not fit that persons of their rank and figure should appear at court unlike their neighbours. Change of raiment, it is likely, they had with them, to put on, instead of that which was cut off; but the loss of their beards would not be so soon repaired; yet in time these would grow again, and all would be well. Let us learn not to lay too much to heart unjust reproaches; after awhile they will wear off of themselves, and turn only to the shame of their authors, while the injured reputation in a little time grows again, as these beards did. God will bring forth thy righteousness as the light, therefore wait patiently for him, Psa 37:6, Psa 37:7.

Some have thought that David, in the indignity he received from the king of Ammon, was but well enough served for courting and complimenting that pagan prince, whom he knew to be an inveterate enemy to Israel, and might now remember how, when he would have put out the right eyes of the men of Jabesh-Gilead, he designed that, as he did this, for a reproach upon all Israel, 1 Sam. Psa 11:2. What better usage could he expect from such a spiteful family and people? Why should he covet the friendship of a people whom Israel must have so little to do with as that an Ammonite might not enter into the congregation of the Lord, even to the tenth generation? Deu 23:3.

I will show kindness unto Hanun the son of Nahash - We do not know exactly the nature or extent of the obligation which David was under to the king of the Ammonites; but it is likely that the Nahash here mentioned was the same who had attacked Jabesh-gilead, and whom Saul defeated: as David had taken refuge with the Moabites, (Sa1 22:3), and this was contiguous to the king of the Ammonites, his hatred to Saul might induce him to show particular kindness to David.

Then said David, I will show kindness to Hanun the son of Nahash,.... Send him a friendly compliment of condolence on the death of his father:

as his father showed kindness unto me; when David was persecuted by Saul, he sent him aid, and invited him into his country for protection it may be, and some way or other showed respect unto him; though not out of real love and friendship to David, but in enmity to Saul, who had defeated him at Jabeshgilead, and had often wars with him: the Jews say (o) the particular kindness was, that when David left his father, mother, and brethren, with the king of Moab, he slew all but one, who fled to the king of the children of Ammon, and was by him saved alive:

and David sent to comfort him by the hand of his servants for his father; for the death of his father; to condole the loss of him, which was the custom of kings in friendship and alliance in former times, and still continues:

and David's servants came into the land of the children of Ammon; even to Rabbah, the metropolis of the nation, and the royal city, where the king kept his court.
