New Defender's Study Bible Notes
2:8 destroy the wall. Nebuchadnezzar had not only taken the city but also had devastated the temple, the palaces and the homes, and even the strong city wall.
2:9 the law is no more. This was not the end of the law, of course (note the words of Jesus in Matthew 5:17-18), but the ministry of the law through the temple and priestly system in Jerusalem.
2:17 fulfilled his word. These terrible afflictions that had come on Israel not only were divine judgments on sin, but were also precise fulfillments of prophecies given some nine hundred years before (e.g., Leviticus 26:14-39; Deuteronomy 28:15-62). Thus the events were vindicating the divine authority of the Scriptures even while the people were denying them.
2:18 apple of thine eye. See note on Deuteronomy 32:10.
2:20 women eat their fruit. Among other things which Jeremiah might have considered inconceivable in the people of God, the thought of starving parents eating their own children surely would have headed the list, yet God had led him to predict it (Jeremiah 19:9), and it had come to pass. See also Lamentations 4:10.
