Matthew Poole and continuators on Esther 9:10

10 The ten sons of Haman, the son of Hammedatha, the enemy of the Jews, slew they; but on the spoil laid they not their hand .

Either because they were desirous it should come into the Kings Treasury: or because they would leave it to their Children, that it might appear that what they did that day was not done out of malice to their Persons and Families, or covetousness of their Estates, but out of meer necessity, and by that great and approved Law of Self-preservation, and that they were ready to mix Mercy with Judgment, and would not deal with their Enemies so ill as it was apparent that their Enemies intended to do against them.
