Matthew Henry's Commentary on Leviticus 19:12
There are some ceremonial precepts in this chapter, but most of these precepts are binding on us, for they are explanations of the ten commandments. It is required that Israel be a holy people, because the God of Israel is a holy God, verse 35. We must make conscience of obeying God's precepts. We are not to pick and choose our duty, but must aim at standing complete in all the will of God. And the nearer our lives and tempers are to the precepts of God's law, the happier shall we be, and the happier shall we make all around us, and the better shall we adorn the gospel.
The friendship of the wicked is more dangerous than their enmity; for none can prevail against God's people if they are not overcome by their inbred lusts; nor can any enchantment hurt them, but the enticements of worldly interests and pleasures. Here is the sin of Israel, to which they are enticed by the daughters of Moab and Midian. Those are our worst enemies who draw us to sin, for that is the greatest mischief any man can do us. Israel's sin did that which all Balaam's enchantments could not do; it set God against them. Diseases are the fruits of God's anger, and the just punishments of prevailing sins; one infection follows the other. Ringleaders in sin ought to be made examples of justice.
