Ezekiel 8:7

The door; the second door, for there were two in the north side. The court; Ezekiel 8:3. Some say it was the court into which the Levites only, not the people, might enter, and round about which were the chambers of the priests. When I looked; probably being at the door of the court, he might espy such a hole in the opposite wall that was toward the temple, whereon were built the treasury chamber, and chambers for tithes, and for other necessaries about the temple worship, and for the priests lodgings, in which these abominations were acted. A hole in the wall, or little blind window, through which he might see somewhat, though not much, of what was done within.
