“the south side.” The Hebrew is literally, “the right side,” but the biblical culture was oriented to the east and thus “ahead” was east, not north. The Temple faced east, so “the right side” is the south side. Leaving “the right side” in the text could be confusing to the Western reader. Thus in Ezekiel’s vision God parked His chariot-throne in the courtyard on the south side of the Temple. This may well have been due to the fact that there was an idol, “the image of jealousy,” in the north gate of the Temple (Ezek. 8:5).
“the house.” The “house” is the house of God, the Temple.
“the cloud filled the inner court.” The cloud indicated the presence of God, and it filled the inner courtyard.
