Esther 5:11-14 New Revised Standard Version (NRSV)
11 and Haman recounted to them the splendor of his riches, the number of his sons, all the promotions with which the king had honored him, and how he had advanced him above the officials and the ministers of the king. 12 Haman added, “Even Queen Esther let no one but myself come with the king to the banquet that she prepared. Tomorrow also I am invited by her, together with the king. 13 Yet all this does me no good so long as I see the Jew Mordecai sitting at the king’s gate.” 14 Then his wife Zeresh and all his friends said to him, “Let a gallows fifty cubits high be made, and in the morning tell the king to have Mordecai hanged on it; then go with the king to the banquet in good spirits.” This advice pleased Haman, and he had the gallows made.
