These verses list the evidence of sins the people committed, such as:
rejecting the Lord
worshiping pagan gods
engaging in sexual misconduct (Jeremiah 7:9; 12:16; Numbers 25:1–3; Deuteronomy 32:21; Joshua 23:7; Zephaniah 1:5; Galatians 4:8)
Idolatry and adultery were closely linked in Israel because both broke an exclusive covenant.
