Ester 7:9

9 Then Harbona, one of the eunuchs attending the king, said, "A pole reaching to a height of fifty cubits That is, about 75 feet or about 23 meters stands by Haman's house. He had it set up for Mordecai, who spoke up to help the king." The king said, "Impale him on it!"

9 Then Harbonah, one of the unsexed servants waiting before the king, said, See, the pillar fifty cubits high, which Haman made for Mordecai, who said a good word for the king, is still in its place in Haman's house. Then the king said, Put him to death by hanging him on it.
