Matthew Poole and continuators on Jeremiah 33:18

18 Neither shall the priests the Levites want a man before me, to offer burnt-offerings, and to kindle meat-offerings, and to do sacrifice continually .

The best Interpreters understand this of a Ministry to abide in the Church to the end of the World according to Matth. 28.20. nor is it unusual for God in the Old Testament to express promise relating to, and to be fulfilled under the Gospel by expressions, and terms proper to the Old Testament, as Isa. 66.23. and in this sence it must be expounded, or restrained to the times immediately following the Captivity, but it is generally understood, as a promise for a Gospel Ministry to succeed the Ministry in the Jewish Church, and to abide to the end of the World.
