Matthew Poole and continuators on 2 Kings 23:9

9 Nevertheless, the priests of the high places came not up to the altar of the LORD in Jerusalem , but they did eat of the unleavened bread among their brethren.

Which Worshipped the True God there.

i. e. Were not suffered to come thither to the exercise of their Priestly function; as a just punishment for the corruption of Gods Worship, and the transgression of so plain and positive a Law of God, Deut. 12. 11. which was much worse in them who had more knowledge to discern Gods mind therein, and more obligations to observe it, and to ingage others to the observation of it. Compare Ezek. 44. 10.

i. e. Of the Meat-Offerings, allotted to the Priests, wherein there was to be no Leaven, Lev. 2. 4, 5, 10, 11. and consequently of other Provisions belonging to the Priests, which by a Synecdoche are contained under this one kind. Thus their Spiritual blemish puts them into the very same state which corporal blemishes brought them, Lev. 21. 17, &c. And thus he mitigates their punishment: he shuts them out from Spiritual Services, but allows them natural and necessary Provisions.
