Therefore I will make Samaria as an heap of the field, and as plantings of a vineyard: and I will pour down the stones thereof into the valley, and I will discover the foundations thereof. I will make Samaria - I will bring it to desolation: and, instead of being a royal city, it shall be a place for vineyards. Newcome observes, that Samaria was situated on a hill, the right soil for a vineyard.
I will discover the foundations thereof - I will cause its walls and fortifications to be razed to the ground.
