The Pentateuch develops God's character in stories of divine creation and destruction, promise and fulfillment, battle and redemption. The laws of Exodus, Leviticus, and Numbers supplement such direct characterization by the impressions provided by YHWH's speech. Speeches always indirectly characterize their speaker by providing the basis for inferring the kind of person who talks this way. So the law codes voiced directly by God provide a powerful impression of the divine character.
