This means, "Act according to your current ways.''
This is actually a severe threat.
إني عامل
I am acting.
according to my way.

You will come to know who it is on whom descends the torment that will cover him with ignominy, and who is a liar!
meaning, between me and you.
وارتقبوا
And watch you!
This means to wait.
إني معكم رقيب
I too am watching with you.
Allah then says,
ولما جاء أمرنا نجينا شعيبا والذين آمنوا معه برحمة منا
وأخذت الذين ظلموا الصيحة فٲصبحوا في ديارهم جاثمين
