Genesis Genesis 20:1–18
Eighteen verses, two hundred eighty-two Hebrew words, and seven canonical first-mentions: prophet, dream, heal, fear-of-God, the verb to sin, integrity, innocence. The prophet enters Scripture as an intercessor for a Gentile king. The Gentile king speaks the integrity-of-heart formula David and Solomon will later inherit. The wombs of Gerar close so that the womb of Sarah can open. Genesis 20 is the canon's densest law-of-first-mention cluster outside Genesis 1–3, and the social location is the thing the chapter forces the reader to see.
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.'
