Esther 5:13 (KJV)

If I have found favour in the sight of the king, and if it please the king to grant my petition, and to perform my request, let the king and Haman come to the banquet that I shall prepare for them, and I will do to morrow as the king hath said.

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.

Nevertheless Haman refrained himself: and when he came home, he sent and called for his friends, and Zeresh his wife.

And Haman told them of the glory of his riches, and the multitude of his children, and all the things wherein the king had promoted him, and how he had advanced him above the princes and servants of the king.

Haman said moreover, Yea, Esther the queen did let no man come in with the king unto the banquet that she had prepared but myself; and to morrow am I invited unto her also with the king.

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.
