'Begun' in the Bible

Haman then related to his wife Zeresh and to all his friends everything that had happened to him. These wise men, along with his wife Zeresh, said to him, "If indeed this Mordecai before whom you have begun to fall is Jewish, you will not prevail against him. No, you will surely fall before him!"

So the Jews committed themselves to continue what they had begun to do and to what Mordecai had written to them.
