I detain the Reader over this verse, just to remark, that though, in the first view, the doctrine may seem harsh, yet the proper apprehension presently clears it up, and stops such a conclusion. The sense of the passage will not be far to gather, if we consider who, and what are meant by a people of no understanding. It doth not mean persons born with weak or no intellect: this is not what is meant in scripture language, when speaking of persons of no understanding. Job explains it at once, when he saith, Behold the fear of the Lord, that is wisdom, and to depart from evil is understanding, Job 28:28. Hence, therefore, by the people the prophet here speaks of, which have no understanding, is meant men that do not, and will not, depart from evil; who know what is good, but do what is evil; who hear of Jesus, but reject and despise him. Concerning such, this scripture saith, He that made them, and he that formed them, inasmuch as they reject Christ, which is the mercy of God, will show them no favor.

11 When the boughs thereof are withered, they shall be broken off: the women come, and set them on fire: for it is a people of no understanding: therefore he that made them will not have mercy on them, and he that formed them will shew them no favour.
