Dafydd Jenkins has been working on Genesis 12-22 and several chiasms will be posted, God willing, soon. Dafydd has identified a large scale chiasm from Genesis 18-21 as follows:
A. Gen 18:9-15 Sarah Laughs (in disbelief)
B. Gen 18:16-33 Abraham Intercedes – emphasis on God’s righteous judgment (Abraham – “will thou also destroy the righteous with the wicked”?)
C. Gen 19:1-11 Immorality in Sodom
D. Gen 19:12-30 Salvation from Sodom
C. Gen 19:31-38 Immorality outside Sodom
B. Gen 20:1-18 Abraham Intercedes – emphasis on God’s righteous judgment (Abimelech – “Lord, will thou slay also a righteous nation”?)
A. Gen 21:1-7 Sarah Laughs (in joy at the birth of Isaac)
