'Happily' in the Bible

And Joshua made peace with them, and {he made a covenant with them} to allow them to live happily, and the leaders of the congregation swore [an oath] to them.

And Zeresh his wife and all of his friends said to him, "Let them make a gallows fifty cubits high, and in the morning tell the king, "Let them hang Mordecai on it; then go with the king to the banquet happily." The advice pleased Haman, so he had the gallows made.
