I. The introduction to this vision of the angels is very magnificent and awakening, v. 4. The prophet, observing the heavens to open, looked, looked up (as it was time), to see what discoveries God would make to him. Note, When the heavens are opened it concerns us to have our eyes open. To clear the way, behold, a whirlwind came out of the north, which would drive away the interposing mists of this lower region. Fair weather comes out of the north, and thence the wind comes that drives away rain. God can by a whirlwind clear the sky and air, and produce that serenity of mind which is necessary to our communion with Heaven. Yet this whirlwind was attended with a great cloud. When we think that the clouds which arise from this earth are dispelled and we can see beyond them, yet still there is a cloud which heavenly things are wrapped in, a cloud from above, so that we cannot order our speech concerning them by reason of darkness. Christ here descended, as he ascended, in a cloud. Some by this whirlwind and cloud understand the Chaldean army coming out of the north against the land of Judah, bearing down all before them as a tempest; and so it agrees with that which was signified by one of the first of Jeremiah's visions (Jer. i. 14, Out of the north an evil shall break forth); but I take it here as an introduction rather to the vision than to the sermons. This whirlwind came to Ezekiel (as that to Elijah, 1 Kings xix. 11), to prepare the way of the Lord, and to demand attention. He that has eyes, that has ears, let him see, let him hear.
