'Behold' in the Bible

The king's servants said to him, "Behold, Haman stands in the court." The king said, "Let him come in."

Then Harbonah, one of the eunuchs who were with the king said, "Behold, the gallows fifty cubits high, which Haman has made for Mordecai, who spoke good for the king, is standing at Haman's house." The king said, "Hang him on it!"
