http://TheNarrowPath.com | This section of scripture is about the glorious New Covenant Jesus established with the Body of Christ (Christians), which is the true Seed or the real Israel that God cares about. Jeremiah's purchase of the field signifies that the remnant would return to Judah, which foreshadows the masses coming to Christ under the N.C. Jeremiah also faces more persecution in these passages.

A New Covenant - Jeremiah 31:31-36

31 "Behold, the days are coming, says the Lord, when I will make a new covenant with the house of Israel and with the house of Judah— 32 not according to the covenant that I made with their fathers in the day that I took them by the hand to lead them out of the land of Egypt, My covenant which they broke, though I was a husband to them,[a] says the Lord. 33 But this is the covenant that I will make with the house of Israel after those days, says the Lord: I will put My law in their minds, and write it on their hearts; and I will be their God, and they shall be My people. 34 No more shall every man teach his neighbor, and every man his brother, saying, 'Know the Lord,' for they all shall know Me, from the least of them to the greatest of them, says the Lord. For I will forgive their iniquity, and their sin I will remember no more."

35 Thus says the Lord,
Who gives the sun for a light by day,
The ordinances of the moon and the stars for a light by night,
Who disturbs the sea,
And its waves roar
(The Lord of hosts is His name):
36 "If those ordinances depart
From before Me, says the Lord,
Then the seed of Israel shall also cease
From being a nation before Me forever."
