'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 recounteth to Zeresh his wife, and to all his friends, all that hath met him, and his wise men say to him, and Zeresh his wife, 'If Mordecai is of the seed of the Jews, before whom thou hast begun to fall, thou art not able for him, but dost certainly fall before him.'

The Jews assembled themselves in their cities throughout all the provinces of King Ahasuerus to strike out against those who were seeking their harm. No one was able to stand before them, for dread of them fell on all the peoples.
