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 11:10-32
The Babel-builders said na'aseh-lanu shem — let us make for ourselves a name. Eight verses later the text answers them with a different shem entirely: eleh toledot Shem — these are the generations of Shem. The line through which the name-promise will travel is literally called Name. Ten generations descend from that line, then narrow into the toledot of Terah and stop in Ur Kasdim with a barren wife, an idol-serving father, and a brother dead in the family's birth-land. Out of those three impossibilities YHWH calls one man into a moledet he must leave for a patris he must seek.
