1 Chronicles 17:1
Now it came to pass, as David sat in his house, that David said to Nathan the prophet, Lo, I dwell in an house of cedars, but the ark of the covenant of the Lord remaineth under curtains. (1 Chronicles 17:1)
Said to Nathan.
 This chapter is almost an exact duplicate of 2 Sam. 7. See also the comments on that chapter.
 Sitting in the palace he had built for himself, David began to realize how inappropriate it was that the services of God should be conducted in a tent. It was his plan that Jerusalem should be the center of worship for the entire nation. Moses had given instruction that there should be one central place of worship (Deut. 12:13, 14). This instruction David now planned to put into effect by building a beautiful temple that would provide due honor to the great God of heaven.
Under curtains.
That is, in a tent.
