Note,

1. Religion is true wisdom, and it makes men wise in every relation. He that conscientiously keeps the law is wise, and he will be particularly a wise son, that is, will act discreetly towards his parents, for the law of God teaches him to do so.
2. Bad company is a great hindrance to religion. Those that are companions of riotous men, that choose such for their companions and delight in their conversation, will certainly be drawn from keeping the law of God and drawn to transgress it, Ps 119:115.
3. Wickedness is not only a reproach to the sinner himself, but to all that are akin to him. He that keeps rakish company, and spends his time and money with them, not only grieves his parents, but shames them; it turns to their disrepute, as if they had not done their duty to him. They are ashamed that a child of theirs should be scandalous and abusive to their neighbours.
