This excerpt is from the blog back in November 2010. Phil explains what David meant by "the beauty of the Lord."
"One thing I have asked from the Lord, that I shall seek: That I may dwell in the house of the Lord all the days of my life, to behold the beauty of the Lord and to meditate in His temple."—Psalm 27:4
As a matter of fact, the Tabernacle where David worshiped was a temporary, makeshift arrangement on mount Moriah. In 2 Chronicles 1:3, we are told that the Tabernacle of Moses' time was kept at Gibeon. Presumably, most of the tabernacle's furnishings were kept in storage there, too—until a generation after David, when Solomon built a more glorious Temple. During David's reign, the tent that was situated on the future temple grounds in Jerusalem was just a temporary place David had prepared as a shelter for the ark of the covenant. There was nothing elaborate about it. In fact, David himself thought the temporary tabernacle was woefully inadequate, and he pleaded in vain with God to let him build a permanent, more elaborate, place of worship (2 Samuel 7:1-13).
