“a standing-stone.” Standing-stones were set up for various reasons, some of them being godly memorials, but here the context is pagan worship. Standing-stones would often be set up as part of the worship of pagan gods, and God has no tolerance for idols. They are harmful in many different ways and are to be destroyed. [For more on standing-stones, see commentary on Gen. 28:18. For more on idols being harmful, see commentary on Deuteronomy 7:5].
