Haman’s death on the execution structure he prepared for Mordecai vividly embodies the psalmic pattern of a trap returning on the one who devised it. Psalm 7 expresses the principle poetically; Esther narrates it with unusually concrete force.

Haman’s death on the execution structure prepared for Mordecai vividly embodies the wisdom principle that the one who digs a pit may fall into it. Esther supplies a concrete narrative instance of Proverbs’ moral pattern without claiming that the proverb was written specifically about Haman.

The execution structure introduced in Esther 5 for Mordecai becomes the instrument of Haman’s death in Esther 7. The callback is explicit and forms one of the book’s clearest measure-for-measure reversals: the device of intended destruction turns back on its maker.
