Everyone seems to want to a find a big chiasm in the Abraham narrative of Genesis. A perusal through the commentaries will reveal an array of options, but I must say I find none of them very satisfactory, since none cover the whole of the Abraham narrative. In attempting to analyze the story for myself, I have what I think holds up better as a plausible chiastic structure for the entire cycle: everything from the “These are the generations of Terah” in 11:27 up to the beginning of the next major segment, “These are the generations of Ishmael” in 25:12.1 The other suggested chiasms can only handle a segment of the whole. They have other problems as well.
