Jeremiah 30:23-24

The Lord’s wrath would break forth on the wicked like a severe storm. It would not slacken until the Lord accomplished all His purpose (cf. Jeremiah 23:19-20). Therefore, the carelessly sinful should feel no false sense of security from these promises of future pardon.

The people did not understand this prophecy fully when the prophet first gave it, but they would in the far distant future. Similarly, God told Daniel to seal up his prophecy because it was not time for His people to understand it yet (Daniel 12:4; Daniel 12:9).
