Genesis Gen 49:5–12; 1 Chr 5:1–2; Heb 7:11–17
Reuben forfeited the firstborn inheritance. Simeon was cursed alongside Levi and then disappeared from Moses's final tribal blessing. Levi, cursed for violence, became the priesthood. Judah was fourth and received the scepter. 1 Chronicles 5:1-2 names the three-way split. Hebrews 7 argues that Jesus's Judah-descent requires a priesthood from outside Aaron's line — recovering through Melchizedek what the Torah had divided.
Luke 3:23
Jesus began his ministry at about thirty years of age. Luke records this detail with a single word of deliberate approximation. Why that age? The answer runs through Levitical law, royal precedent, prophetic timeline, and the logic of the incarnation itself.
Deuteronomy 31:12
