Theological exegesis demands engagement with the biblical text. Much of the current discussion regarding this topic tends to remain in the realm of theory and method without much ‘exegetical showing’. Taking a cue from Brevard Childs' understanding of the Old Testament as Christian Scripture, this article provides an example of theological exegesis with Isaiah as the focus text. The intertextual relationship between Isaiah 6 and 61 is engaged in its literary/canonical fixity. From this fixity, the figural potentiality of this intertextual relationship is explored in light of the two-testament canon and its shared subject matter.
