'Posing' in the Bible

In every province and city, wherever the king's edict and his law came, there was gladness and joy for the Jews, a banquet and a {holiday}, and many of the people from the country [were] posing as Jews because the fear of the Jews had fallen on them.

Then I said, "Ah, Lord Yahweh, they are saying about me, '[Is] he not posing a parable?'"
