make a large tent

This is background information about the tent the Israelites were to make as a place to worship God. (See: rc://en/ta/man/translate/writing-background)

the room behind the curtain

This room was hidden by the curtain. Some languages would call this room, “the room in front of the curtain.”

where God was

If this phrase would lead people to think that God was limited to living in the tent, it could be translated as, “where God revealed Himself to humans.”
