Zedekiah, king of Judah (597-587 B.C.) consistently expected that God would bring a last minute reprieve, and he and his people would not be conquered by the Babylonians. He underestimated the sin of his people, and he underestimated God's power to deal with that.
For this reason, the prophet Jeremiah consistently has to warn him that there will be no reprieve. Into exile they will go.
