Jeremiah 32:38-40

He would reestablish a covenant relationship with them, give them all a faithful heart, and they would then always fear Him (cf. Jeremiah 31:31-34). The result would be blessing for them and for their descendants. His (new) covenant with them would be everlasting, a promise not mentioned in the New Covenant passage in the preceding chapter (cf. Ezekiel 36:24-32). He would always do them good, and they would always reverence Him, not just know Him (Jeremiah 31:34).
