Exodus Exodus 15:1-21
Israel's first hymn — the warrior named, the incomparable God, the first proclamation of his eternal reign — sung at the Red Sea and again, at the end, by the redeemed beside the sea of glass.
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.
Obadiah 1:1–21
Obadiah is twenty-one verses long. It opens with one brother's betrayal of another on a specific day (586 BC) and ends with the declaration לַיהוָה הַמְּלוּכָה — a phrase Psalm 22 also makes, and that appears nowhere else in the canon. The little book carries a large argument.
