Matthew Henry's Commentary on Leviticus 19:31
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.
