Take Alter's treatment of the cycle of stories in which the first two matriarchs, Sarah and Rebekah, conspire against elder sons for the benefit of younger ones. Sarah insists that Abraham drive Ishmael, his firstborn, and Ishmael's mother, Hagar, into the desert to die, to protect the inheritance of Sarah's son, Isaac. Rebekah tells her son Jacob to trick his father, the now elderly Isaac, into giving him a blessing rightfully owed to Esau, Jacob's ever-so-slightly older twin brother. The matriarchs' behavior is indefensible, yet God defends it. He instructs Abraham to do as Sarah says, and after Jacob takes flight from an enraged Esau God comes to Jacob in a dream, blesses him, and tells him that he, too, like Abraham and Isaac before him, will father a great nation.Alter doesn't try to explain away the paradox of a moral God sanctioning immoral acts. Instead he lets the Bible convey the seriousness of the problem. When Abraham balks at abandoning Ishmael and Hagar, God commands, "Whatever Sarah says to you, listen to her voice." Rebekah, while instructing Jacob on how to dress like Esau so as to steal his blessing, echoes God's phrase -- listen to my voice" -- not once but twice in an effort to reassure him. As we read on in Alter's translation, we realize that the word "voice" ("kol" in Hebrew) is one of his "key words," that if we could only manage to keep track of all the ways it is used it would unlock new worlds of meaning. In the story of Hagar and Ishmael, God's messenger will tell Hagar that God will save them because he has heard the voice of the crying boy. And the all but blind Isaac will recognize the sound of Jacob's voice, so that although his younger son stands before him with his arms covered in goatskin (to make them as hairy as Esau's), and has even put on his brother's clothes (to smell more like a hunter), Isaac nearly grasps the deceit being perpetrated against him.

Alter's translation puts into practice his belief that the rules of biblical style require it to reiterate, artfully, within scenes and from scene to scene, a set of "key words," a term Alter derives from Buber and Franz Rosenzweig, who in an epic labor that took nearly 40 years to complete, rendered the Hebrew Bible into a beautifully Hebraicized German. Key words, as Alter has explained elsewhere, clue the reader in to what's at stake in a particular story, serving either as "the chief means of thematic exposition" within episodes or as connective tissue between them.
