I. How this discovery is made. God, in vision, brought Ezekiel to the door of the court, the outer court, along the sides of which the priests' lodgings were. God could have introduced him at first into the chambers of imagery, but he brings him to them by degrees, partly to employ his own industry in searching out these mysteries of iniquity, and partly to make him sensible with what care and caution those idolaters concealed their idolatries. Before the priests' apartments they had run up a wall, to make them the more private, that they might not lie open to the observation of those who passed by—a shrewd sign that they did something which they had reason to be ashamed of. He that doth evil hates the light. They were not willing that those who saw them in God's house should see them in their own, lest they should see them contradict themselves and undo in private what they did in public. But, behold, a hole in the wall, (v. 7), a spy-hole, by which you might see that which would give cause to suspect them. When hypocrites screen themselves behind the wall of an external profession, and with it think to conceal their wickedness from the eye of the world and carry on their designs the more successfully, it is hard for them to manage it with so much art by that there is some hole or other left in the wall, something that betrays them, to those who look diligently, not to be what they pretend to be. The ass's ears in the fable appeared from under the lion's skin. This hole in the wall Ezekiel made wider, and behold a door, v. 8. This door he goes in by into the treasury, or some of the apartments of the priests, and sees the wicked abominations that they do there, v. 9. Note, Those that would discover the mystery of iniquity in others, or in themselves, must accomplish a diligent search; for Satan has his wiles, and depths, and devices, which we should not be ignorant of, and the heart is deceitful above all things; in the examining of it therefore we are concerned to be very strict.
