L. Michael Morales's volume, Who Shall Ascend the Mountain of the Lord: A Biblical Theology of Leviticus, is chock full of insights. Consider the following
The wayyiqtol form with which the book [Leviticus], and from which it derives its Hebrew title, sets the following legislation within a narrative context. Thematically, the opening wayyiqrā’ (And-he-called) sets the entire book of Leviticus within the development of God’s redemptive dealings, as the following chart illustrates.
YHWH God called to Adam [in the garden of Eden] Genesis 3:9
God called to him [Moses] from within the bush Exodus 3:4
YHWH called to him [Moses] from the mountain Exodus 19:3
YHWH called to Moses from within the cloud Exodus 24:16
YHWH called to Moses and spoke to him from the Leviticus 1:1
tent of meeting
More particularly for our purposes, the wayyiqtol links Leviticus to the narrative context of the ending of Exodus, as a continuation of it. We may, therefore, turn to the close of Exodus in order to position the legislation leading up to the inauguration of the tabernacle cultus (Lev. 1–10).
