God was incredibly specific with how the tabernacle should be built, what materials to use, dimensions etc. Why was He not as specific when Solomon built the temple?
Interesting question. God gave Moses specific plans on how the Tabernacle was to be constructed (Exodus 26) and what it would be used for. Maybe this was due to the fact that the Ark of the Covenant of God was to be put there. The tent was mobil.
I don’t know why God didn’t give Solomon specific details for the construction of the Temple. He was chosen by God to build his Temple. Solomon purpose to build a Temple, for the name of the Lord, and a royal palace for himself. 2 Chronicles 2:1 ; and 1 Chronicles 6:32
