Albert Barnes Commentary 2 Samuel 7:6

"for I have not dwelt in a house since the day that I brought up the children of Israel out of Egypt, even to this day, but have walked in a tent and in a tabernacle." — 2 Samuel 7:6 (ASV)

Have walked - Implying the frequent moving of the tabernacle in the times of the Judges, as opposed to a settled resting in one place. The word "tent" refers especially to the outward covering of skins, etc.; the "tabernacle" denotes the framework of boards and bars. Observe the constant reference to the Exodus and to the details given in the books of Moses.
