In "Word Focus" Glenn McClure writes:

The word dwelt is literally translated “tabernacled.” It is from the word “tent.” “To dwell in a tent with one” means the same as to be in his family, so when John said He tabernacled with them, he meant that Christ was with them as a friend and as one of the family, so that they had complete opportunity of becoming familiarly acquainted with Him and could not be mistaken in supposing that He was really a man.
