Jamieson, Fausset and Brown on 1 Chronicles 17:5

5. I ... have gone from tent to tent, and from one tabernacle to another--The literal rendering is, "I was walking in a tent and in a dwelling." The evident intention (as we may see from 1Ch 17:6) was to lay stress upon the fact that God was a Mithhatlek (a travelling God) and went from one place to another with His tent and His entire dwelling (the dwelling included not merely the tent, but the fore-courts with the altar of burnt offerings, &c.) [Bertheau].
