1 Kings 8:10

the cloud filled the house of the Lord Thecloud was the veil which hid the glory of the Lord. The article denotes that it was something well known and perhaps permanent. Cf. Exodus 40:34-35 where it is said -the cloud covered the tent of meeting and the glory of the Lord filled the tabernacle, and Moses was not able to enter into the tent of meeting because the cloud abode thereon." This was the token that God had taken up His abode there, and thus a standing lesson was before the eyes of the people concerning the fact of the Incarnation. Josephus says of this cloud that -it produced in the minds of all the notion and thought that God had come down into the Temple, and was gladly tabernacling therein." It was indeed the Shechinah, the dwellingplace of God.
