1 Samuel 30:26

He sent of the spoil unto the elders of Judah Partly in gratitude for their former favours to him; and partly in policy to engage their affections to him. Behold a present for you In the Hebrew, a blessing. So he calls the present, because it was a token that he wished all prosperity to them, who had been kind to him in his banishment, and had helped to maintain and protect him. Of the spoil of the enemies of the Lord The success of David in this pursuit of the Amalekites, will, upon examination, appear so extraordinary that it is not easy to account for it, otherwise than from the peculiar superintendence of Providence over David and his concerns. Indeed, the interposition of Providence is seen in every circumstance of this adventure; the number, the perseverance, the issue. That they might not think their number did the work, God reduced them to four hundred, as he did Gideon's company to three, Judges 7. Many others have been as fortunate in surprising, and as successful in slaughtering their enemies; but to have strength both for the slaughter and pursuit, for so many hours together, is altogether extraordinary. But what is yet more remarkable is, that he should recover all the captives unhurt, out of the hands of a people so abandoned, and so execrable as the Amalekites! We have intimated that these Amalekites, being poor, spared their captives from a prospect of profiting greatly by the sale of them. Others, however, perhaps with as much reason, think they only respited their cruelty to execute it to more advantage at their leisure. How beautiful a contemplation is it to observe the signal goodness of God and malignity of man co-operating to the same end! See Delaney.
