Esther 5:14

Then said Zeresh, his wife, and all his friends unto him, Let a gallows be made of fifty cubit high, the great height serving to emphasize the execution and its disgrace, and tomorrow speak thou unto the king that Mordecai may be hanged thereon, there being no doubt in their mind that this request would readily be granted. Then go thou in merrily with the king unto the banquet, his enjoyment undisturbed by a single thought of the hateful Jew. And the thing pleased Haman; and he caused the gallows to be made, erected before his very house, all ready for the execution which he hoped to bring about on the next day. Thus the supposed luck of the godless makes them secure and prepares them for the destruction which the Lord has appointed for them.
