John Wesley on Jeremiah 3:16

Multiplied - After the growth of the church under the Messiah. The ark - That whole worship with all the rites and ceremonies belonging to it shall cease, Christ being come, who was the substance of what the ark, and all other rites shadowed. Covenant - Called also the ark of the testimony, because the two tables of the law, which were the testimony, or witness of the covenant were in it. Any more - It shall be no more in use; neither shall men trouble their thoughts about it, or mention it.
