Charles Ellicott Commentary Ezekiel 10:4

"And the glory of Jehovah mounted up from the cherub, [and stood] over the threshold of the house; and the house was filled with the cloud, and the court was full of the brightness of Jehovah`s glory." — Ezekiel 10:4 (ASV)

The glory of the Lord went up from the cherub. —As in Ezekiel 10:2, the singular, cherub, is used instead of the usual plural. Here it is thought to designate not the four living creatures of the vision, but the cherubim overshadowing the mercy seat, and to indicate that the manifestation of the Divine presence now left the Holy of Holies and went to the threshold of the door of the house, in preparation for leaving it entirely.

The expression is obscure, since the place of the manifestation of the Divine presence in the Most Holy Place is usually described as between the cherubim (Exodus 25:22; Numbers 7:89; Psalms 80:1; Psalms 99:1, and others). Of the main point, however, there can be no doubt—that the Divine presence is represented as in the act of leaving the Temple. The house was filled with the cloud, and the court was full of the brightness of the Lord’s glory as He departed, in striking contrast with the similar manifestations (Exodus 40:34–35; 1 Kings 8:10–11), when God accepted the tabernacle and the Temple as His special place of dwelling.
