v1: [I gave faithless Israel her certificate of divorce and sent her away because of all her adulteries. Yet I saw that her unfaithful sister Judah had no fear; she also went out and committed adultery.] (Jer 3:8). Jeremiah 3:8 tells us that God has divorce the non-dividic northern kingdom because of your adulterous act, but God didn’t divorce the southern kingdom, because of God’s covenant with David. There is why in v1 says [Where is your mother’s certificate of divorce?]. Your mother is referring to the southern kingdom. God didn’t divorce them, however because of their transgression, they are separated from God, temporary.
v2: [dry up the sea] God dried up the Red Sea (Ex 14:21). [turn rivers into a desert] God opened the river of Jordan by turning it into dry land. (Josh 4:23). [their fish rot for lack of water] God killed the fish in Egypt by turning water into blood (Ex 7:18-21).
v2: God called the Jews to return from Babylon to Judah, however no one answer. So God reminded them how God redeemed the Jews out of Egypt.
