Romans 11:3 - Coke's Commentary on the Holy Bible

Digged down thine altars— It hence seems, that though, according to the law there was only one altar for sacrifice, and that in the place where God had fixed his peculiar residence; yet, by some special dispensation, pious persons in the ten tribes built altars elsewhere. It is well known, at least, that Samuel and Elijah had done it; and perhaps they were either kept up, or others raised on the same spots of ground. Baal, or Baalim, (see Romans 11:4.) was a general name, whereby the false gods and idols were denoted in Scripture. See Judges 11:11-13, Hosea 11:2. Locke and Doddridge.
