As we saw concerning Chronicles in chapter 2, the Old Testament already does in principle what Paul is doing here: reworking the past to speak to the present. That interpretive conviction is seen time and time again throughout Second Temple Jewish literature where the past needs to be rethought in view of the present. This can be counterintuitive for modern readers: it is the very act of altering the past to address present circumstances that ensures its continuation as the active and abiding Word of God, not a relic of a bygone era. That is why the Chronicler does what he does with Samuel-Kings, and it is why Paul does what he does with the Abraham story. The text is not the master: it serves a goal. For Paul, that goal is the absolute and uncompromised centrality of what God has done here and now in the crucified and risen Christ.
