YHWH's Statutes, Israel's Distinctive Walk, and Life
Paul does not merely discuss “the law” abstractly—he quotes Leviticus 18:5 itself in both Galatians and Romans. Reading the original covenant-life statement first makes it possible to see exactly what Paul is reusing and where interpretive questions begin.
Where this fits in the story: Exodus covenant identity and YHWH's deliverance from Egypt stand behind Israel's call not to walk in Egyptian/Canaanite practices but in YHWH's statutes.
Where Scripture takes it next: Galatians 3:12 — Certain explicit quotation. Paul quotes Leviticus 18:5.
