“But draw near here, you sons of a sorceress, you offspring of adulterers and prostitutes. Whom do you mock? Against whom do you make a wide mouth and stick out your tongue? Aren’t you children of disobedience and offspring of falsehood, you who inflame yourselves among the oaks, under every green tree; who kill the children in the valleys, under the clefts of the rocks? Among the smooth stones of the valley is your portion. They, they are your lot. You have even poured a drink offering to them. You have offered an offering. Shall I be appeased for these things?
