'Able' in the Bible

Then his wife Zeresh and all his friends said to him, Let a pillar, fifty cubits high, be made ready for hanging him, and in the morning get the king to give orders for the hanging of Mordecai: then you will be able to go to the feast with the king with a glad heart. And Haman was pleased with the suggestion, and he had the pillar made.

And Haman gave his wife Zeresh and all his friends an account of what had taken place. Then his wise men and his wife Zeresh said to him, If Mordecai, who is starting to get the better of you, is of the seed of the Jews, you will not be able to do anything against him, but you will certainly go down before him.
