Matthew Poole and continuators on 2 Chronicles 24:22

22 Thus Joash the king remembred not the kindness which Jehojada his father had done to him, but slew his son: And when he died, he said, The LORD look upon it, and require it .

i. e. Make inquisition for my innocent blood. Which he did not wish from any desire of private revenge, with which so wise and good a man would never be willing to die; but partly from a zeal to publick Justice and the punishment of such gross wickedness; and partly to deter them, if possible, from compleating their murderous intentions. But these words may as well be rendred indicatively as optatively, The Lord will look upon it, and require it, i. e. He will examine this action, and require satisfaction from you for it.
