Therefore I was left alone, and saw this great vision, and there remained no strength in me: for my comeliness was turned in me into corruption, and I retained no strength.
My comeliness - literally, vigour, i:e., lively expression and colour.
Was turned in me into corruption - deadliness, i:e., death-like paleness. Such was the usual effect on those to whom a manifestation of the heavenly beings was made (Daniel 5:6; Daniel 7:28).
