Albert Barnes Commentary 2 Samuel 7:23

"And what one nation in the earth is like thy people, even like Israel, whom God went to redeem unto himself for a people, and to make him a name, and to do great things for you, and terrible things for thy land, before thy people, whom thou redeemest to thee out of Egypt, [from] the nations and their gods?" — 2 Samuel 7:23 (ASV)

The nations and their gods - that is, the people and the idols of Canaan.
