Let us here observe, 1. That is becomes good people to be neighbourly, and especially to be grateful. David will pay respect to Hanun because he is his neighbour; and religion teaches us to be civil and obliging to all, to honour all men, and to be ready to do all offices of kindness to those we live among; nor must difference in religion be any obstruction to this. But, besides this, David remembered the kindness which his father showed to him. Those that have received kindness must return it as they have ability and opportunity: those that have received it from the parents must return it to the children when they are gone. 2. That, as saith the proverb of the ancients, Wickedness proceedeth from the wicked, Sa1 24:13. The vile person will speak villany, and the instruments of the churl will be evil, to destroy those with lying words that speak right, Isa 32:6, Isa 32:7. Those that are base, and design ill themselves, are apt to be jealous and to suspect ill of others without cause. Hanun's servant suggested that David's ambassadors came as spies, as if so great and mighty a man as David needed to do so mean a thing (if he had any design upon the Ammonites, he could effect it by open force, and had no occasion for any fraudulent practices), or as if a man of such virtue and honour would do so base a thing. Yet Hanun hearkened to the suggestion, and, against the law of nations, treated David's ambassadors villainously. 3. Masters ought to protect their servants, and with the greatest tenderness to concern themselves for them if they come by any loss or damage in their service. David did so for his ambassadors, Ch1 19:5. Christ will do so for his ministers; and let all masters thus give unto their servants that which is just and equal.
