'Ready' in the Bible

Now if you are ready so that {when} you hear the sound of the horn, the flute, the lyre, [the] trigon, [the] harp and [the] drum and all kinds of music, you fall down and you worship the statue that I have made, [that will be good]. But if you do not worship it, {immediately} you will be thrown into the midst of the furnace of blazing fire, and {who is the god} who will rescue you from my hands?"
