Moses
Exodus 40:37ESV·traditional attribution

But if the cloud was not taken up, then they did not set out till the day that it was taken up.

Matthew Henry Presbyterian @wholebiblehenry

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.

Exo 40:34-38 When the sanctuary, that had been built for the Lord for a dwelling in Israel, had been set up with all its apparatus, “the cloud covering the tabernacle, and the glory of Jehovah filled the dwelling,” so that Moses was unable to enter.
