Because of the grace we live in, I don't think we realize the harshness of God's Old Testament commands. When I read this, I didn't see a lot in it. His parents talked to him separately, and chastened him together after he wouldn't listen. That statement brought a lot of memories back to me. Our kids used to play pillar to post with us.
All kids do it.
And there were plenty of times I would like to have stoned some of them myself. To divide them. They manipulate to do what they want. Such things can be the seeds of gluttony. But it seems these parents in Deuteronomy did it right.
