The recurring structural phrase in Genesis: 'These are the toledoth of...' — introducing each major section. Literally 'begettings' or 'what was generated,' it organizes the book around origins and outcomes.
The phrase 'these are the generations of' appears 11 times in Genesis, structuring the book. Each toledoth section recounts what flowed from a key person or event — a theology of origins and consequences.
Matthew 1:1's 'book of the genealogy of Jesus Christ' deliberately echoes the Genesis toledoth formula. Jesus is the culminating 'generation' — what all the preceding begettings were pointing toward.
