sinned against the LORD … who had brought them out of the land of Egypt: Their downfall came from repeatedly being unfaithful. Instead of staying loyal to their Redeemer, they worshiped other gods.
Israel's rescue from Egypt is a common theme in the Old Testament. It appears in:
the poetic writings (Exodus 15:1–18; Psalms 77:13–20; 105:26–45; 106:7–12; 114:1–8; Habakkuk 3:3–15),
the prophets (Isaiah 63:11–14; Jeremiah 2:1–8; 32:21–23; Ezekiel 20:10–12; Micah 6:4), and
the historical writings (Joshua 3:5; 4:14, 18–24; 1 Samuel 12:6).
