Esther 5:9; Esther 5:14

9 Then went Haman forth that day joyful and with a glad heart: but when Haman saw Mordecai in the king's gate, that he stood not up, nor moved for him, he was full of indignation against Mordecai.

14 Then said Zeresh his wife and all his friends unto him, Let a gallows be made of fifty cubits high, and to morrow speak thou unto the king that Mordecai may be hanged thereon: then go thou in merrily with the king unto the banquet. And the thing pleased Haman; and he caused the gallows to be made.
