- Insight from Butler's Daily Bible Reading: Deuteronomy 6—Teaching the Law. •Why to teach: the objective of teaching was to get people to “do” (v. 1) the law. Practical application to conduct should be the object of all spiritual teaching and preaching. •Who to teach: children were the special objects of the teaching. •When to teach: at all times (such as when you get up, when you are sitting in the house, when walking, when going to bed, etc.) and in all ways (by words and also by deeds such as posting the word on the walls of your house and other places). •What to teach: all the law, the submission to the laws, and the blessings from the law.
