2 Samuel 6:7

He died — This may seem very severe, considering his intention was pious, and his transgression not great. But, besides that, men are improper judges of the actions of God; and that God's judgments are always just, though sometimes obscure: it is reasonable, God should make some present examples of his high displeasure against sins, seemingly small; partly, for the demonstration of his own exact and impartial holiness; partly, for the establishment of discipline, and for the greater terror and caution of mankind, who are very prone to have slight thoughts of sin, and to give way to small sins, and thereby to be led on to greater; all which is, or may be prevented by such instances of severity: and consequently there is more of God's mercy, than of his justice, in such actions, because the justice is confined to one particular person, but the benefit of it common to mankind in that, and all future ages.
