Genesis Genesis 26:1-33
Genesis 26 is the only chapter in the Torah where Isaac is the active patriarch. The famine, the lie at Gerar, the hundredfold harvest, the four wells, the night theophany at Beersheba, and the treaty with Abimelech stage a deliberate replay of Abraham's life. But two verses make this chapter's contribution canonical: Genesis 26:5 (the fullest pre-Sinai cluster of Sinai-legal vocabulary in the canon — four legal nouns stacked together, citing the Akedah-oath) and Genesis 26:24 (the first installment of «I am the God of Abraham your father,» the formula Jesus deploys against the Sadducees and Stephen quotes at his death).
Genesis 12:10-13:18
A heavy famine drives Abram down; a heavy wealth carries him back up. Between the two, Yahweh strikes Pharaoh with great plagues — the first plague-word in the canon. Then Lot lifts his eyes and chooses the plain that is about to burn, and Yahweh tells Abram to lift his eyes and see the land he will give to his seed forever. Gen 12:10–13:18 is the miniature Exodus that frames the covenant's first 'forever.'
