Here is a model for “legal theology,” a way of learning and teaching about God that arises in and responds to the desire to understand the significance of law: a son is moved to ask “what is the meaning” of the law followed by his father, and the father is commanded to explain by teaching about God's deliverance. There are three similar commands in Exodus (Exodus 12:26, 13:8, 13:14), linked in tradition, where sons wonder and fathers are commanded to explain how a particular law signifies God's redemption. These four commands in Exodus and Deuteronomy indicate a method for legal theology.
