17.  The multitude of the hearers was confounded;—it was a second confusion, in the room of that first evil one at Babylon.  For in that confusion of tongues there was division of purpose, because their thought was at enmity with God; but here minds were restored and united, because the object of interest was godly.  The means of falling were the means of recovery.  Wherefore they marvelled, saying Acts ii. 8., How hear we them speaking?  No marvel if ye be ignorant; for even Nicodemus was ignorant of the coming of the Spirit, and to him it was said, The Spirit breatheth where it listeth, and thou hearest the voice thereof, but canst not tell whence it cometh, and whither it goeth John iii. 8:  (R.V.) The wind bloweth:  (Marg.) Or, The Spirit breatheth.  It is impossible to preserve the double meaning in English.; but if, even though I hear His voice, I know not whence he cometh, how can I explain, what He is Himself in substance?
