I. They were not peculiar and entire for God, as they should have been, v. 8. 1. They did not distinguish themselves from the heathen, as God had distinguished them: Ephraim, he has mingled himself among the people, has associated with them, and conformed himself to them, and has in a manner confounded himself with them and lost his character among them. God had said, The people shall dwell alone; but they mingled themselves with the heathen and learned their works, Ps. xvi. 35. They went up and down among the heathen, to beg help of one of them against another (so some); whereas, if they had kept close to God, they would not have needed the help of any of them. 2. They were not entirely devoted to God: Ephraim is a cake not turned, and so is burnt on one side and dough on the other side, but good for nothing on either side. As in Ahab's time, so now, they halted between God and Baal; sometimes they seemed zealous for God, but at other times as hot for Baal. Note, It is sad to think how many, who, after a sort, profess religion, are made up of contraries and inconsistencies, as a cake not turned, a constant self-contradiction, and always in one extreme or the other.
