Matthew Poole and continuators on Jeremiah 31:36

36 If those ordinances depart from before me, saith the LORD, then the seed of Israel shall also cease, from being a Nation before me for ever.

There are ordinances of Worship, which are God's Laws relating to his Worship, and Ordinances of Iustice, which are Gods laws, for the executing civil Justice, and Ordinances of Nature, which are Gods establishments for the working of natural causes in their order; these are those here spoken of,

Which shall hold and continue to the dissolution of the world, the continuance of which God pawneth as a pledge of the continuance of Israel as a Nation all the dayes (so it is in the Hebrew) that is many dayes, or all the dayes they shall keep close with me, or which I have appointed, if we interpret it (as in our version) for ever it must be understood not of Israel according to the flesh, but, of the Church, the true Israel of God, which shall never fail.
