Matthew Henry on Exodus 40:34–end
As when, in the creation, God had finished this earth, which he designed for man's habitation, he made man, and put him in possession of it, so when Moses had finished the tabernacle, which was designed for God's dwelling-place among men, God came and took possession of it.
